This is a training module for the Altera Cyclone II FPGA
Welcome to this module on the Cyclone II family FPGA from Altera. The module overviews the major features of the Cyclone II family FPGA.
Programmable logic is loosely defined as a device with configurable logic and flip-flops linked together with programmable resources that control the interconnections. User-programmable memory cells control and define the function that the logic performs and how the various logic functions are interconnected. Thus a wide range of sequential circuits can be implemented on a low-cost PLD. Though various devices use different architectures, all are based on this fundamental idea.
FPGAs have gained rapid acceptance over the past decade because users can apply them to a wide range of applications: random logic, integrating multiple SPLDs, device controllers, communication encoding and filtering, small- to medium-size systems with SRAM blocks, and many more. Another interesting FPGA application is prototyping designs to be implemented in gate arrays by using one or more large FPGAs . An application only beginning development is the use of FPGAs as custom computing machines. This involves using the programmable parts to execute software, rather than compiling the software for execution on a regular CPU.
Altera understands programmable devices are part of a bigger picture, and that true design success requires an array of other tools. To that end, Altera complements the complex programmable logic devices (CPLDs) and field programmable gate arrays (FPGAs) with sophisticated software tools, pre-verified and configurable intellectual property (IP) cores, a soft-core processor – Nios II, development kits, and reference designs. Our comprehensive solution portfolios result in a faster, simplified design process and, in turn, faster time to market and lower development costs. With Altera® solutions, you can undertake your design, confident that you’ll be able to meet your unique application design goals.
Following the immensely successful first-generation Cyclone® device family, Altera® Cyclone II FPGAs extend the low-cost FPGA density range to 68,416 logic elements (LEs) and provide up to 622 usable I/O pins and up to 1.1 Mbits of embedded memory. Cyclone II FPGAs are manufactured on 300-mm wafers using TSMC's 90-nm process to ensure rapid availability and low cost. By minimizing silicon area, Cyclone II devices can support complex digital systems on a single chip at a cost that rivals that of ASICs. Altera’s low-cost FPGAs—Cyclone II FPGAs, offer high performance and the low power consumption.
Altera Cyclone II FPGAs extend the low-cost FPGA density range to 68,416 logic elements (LEs) and provide up to 622 usable I/O pins and up to 1.1 Mbits of embedded memory. Embedded multiplier block can implement up to either two 9 × 9-bit multipliers, or one 18 × 18-bit multiplier with up to 250-MHz performance. Embedded multipliers are arranged in columns across the device. Cyclone II devices support a broad range of external memory interfaces, such as SDR SDRAM, DDR SDRAM, DDR2 SDRAM, and QDRII SRAM. Dedicated clock delay control circuitry allows Cyclone II devices to interface with an external memory device at clock speeds up to 167 MHz/333 Mbps for DDR and DDR2 SDRAM devices and 167 MHz/667 Mbps for QDRII SRAM devices. Each Cyclone II device has up to four PLLs, supporting advanced capabilities such as clock switchover and programmable switchover. These PLLs offer clock multiplication and division, phase shifting, and programmable duty cycle and can be used to minimize clock delay and clock skew, and to reduce or adjust clock-to-out and set-up times.
Altera® Cyclone II FPGAs extend the low-cost FPGA density range to 68,416 logic elements (LEs) and provide up to 622 usable I/O pins and up to 1.1 Mbits of embedded memory. Cyclone II devices include a powerful FPGA feature set optimized for low-cost applications including a wide range of density, memory, embedded multiplier, and packaging options. Cyclone II devices support a wide range of common external memory interfaces and I/O protocols required in low-cost applications.
Vertical migration means that you can migrate to devices whose dedicated pins, configuration pins, and power pins are the same for a given package across device densities. Cyclone II devices support vertical migration within the same package (for example, you can migrate between the EP2C35, EPC50, and EP2C70 devices in the 672-pin FineLine BGA package).
Cyclone II devices support the Nios II embedded processor which allows to implement custom-fit embedded processing solutions. Cyclone II devices can also expand the peripheral set, memory, I/O, or performance of embedded processors. Single or multiple Nios II embedded processors can be designed into a Cyclone II device to provide additional co-processing power or even replace existing embedded processors in your system. Using Cyclone II and Nios II together allow for low-cost, high-performance embedded processing solutions, which allow you to extend your product's life cycle and improve time to market over standard product solutions.
Nios and Nios II are the Soft Processor IP solutions from Altera for Embedded Applications. The table demonstrates the resource utilization or Logic Element usage summary for Nios and Nios II Embedded Processor within Cyclone II FPGAs. Nios II processor adds the advantage in better performance with less silicon utilization and comparatively low Cost.
Altera’s Quartus II Design Software supports all the Cyclone II family Devices. Quartus II software has full integrity with advanced tool Such as SOPC Builder and DSP Builder for Embedded and DSP Applications respectively.
Cyclone® II devices contain a two-dimensional row- and column-based architecture to implement custom logic. Column and row interconnects of varying speeds provide signal interconnects between logic array blocks (LABs), embedded memory blocks, and embedded multipliers.
The logic array consists of LABs, with 16 logic elements (LEs) in each LAB. An LE is a small unit of logic providing efficient implementation of user logic functions. LABs are grouped into rows and columns across the device. Cyclone II devices range in density from 4,608 to 68,416 LEs. Each LAB consists of 16 Les, LAB control signals, LE carry chains, Register chains, and Local interconnect.
The smallest unit of logic in the Cyclone II architecture, the LE, is compact and provides advanced features with efficient logic utilization. Each LE features a four-input look-up table (LUT), which is a function generator that can implement any function of four variables, a programmable register, a carry chain connection, a register chain connection, the ability to drive all types of interconnects: local, row, column, register chain, and direct link interconnects, support for register packing, and support for register feedback.
Cyclone II devices have embedded multiplier blocks optimized for multiplier-intensive digital signal processing (DSP) functions, such as finite impulse response (FIR) filters, fast Fourier transform (FFT) functions, and discrete cosine transform (DCT) functions. The embedded multiplier consists of multiplier block, input and output registers, input and output interfaces. Each Cyclone II device has one to three columns of embedded multipliers that efficiently implement multiplication functions.
Embedded multipliers can operate at up to 250 MHz (for the fastest speed grade) for 18 × 18 and 9 × 9 multiplications when using both input and output registers. An embedded multiplier can be configured to support a single 18 × 18 multiplier for operand widths up to 18 bits. All 18-bit multiplier inputs and results can be registered independently. The multiplier operands can accept signed integers, unsigned integers, or a combination of both. An embedded multiplier can be configured to support two 9 × 9 independent multipliers for operand widths up to 9-bits. Both 9-bit multiplier inputs and results can be registered independently. The multiplier operands can accept signed integers, unsigned integers or a combination of both.
Cyclone® II devices support a broad range of external memory interfaces such as SDR SDRAM, DDR SDRAM, DDR2 SDRAM, and QDRII SRAM. Dedicated clock delay control circuitry allows Cyclone II devices to interface with an external memory device at clock speeds up to 167 MHz/333 Mbps for DDR and DDR2 SDRAM devices and 167 MHz/667 Mbps for QDRII SRAM devices. The easiest way to interface to external memory devices is by using one of the Altera® external memory IP cores, such as DDR2 SDRAM Controller MegaCore® Function, DDR SDRAM Controller MegaCore Function, QDRII SRAM Controller MegaCore Function and OpenCore® Plus evaluations of these cores are available for free to Quartus® II Web Edition software users.
The Cyclone II embedded memory consists of columns of M4K memory blocks. The M4K memory blocks include input registers that synchronize writes and output registers to pipeline designs and improve system performance. The output registers can be bypassed, but input registers cannot. Each M4K block can implement various types of memory with or without parity, including true dual-port, simple dual-port, and single-port RAM, ROM, and first-in first-out (FIFO) buffers.
The proliferation of I/O standards and the need for improved I/O performance have made it critical that low-cost devices have flexible I/O capabilities. Selectable I/O capabilities such as SSTL-18, SSTL-2, and LVDS compatibility allow Cyclone® II devices to connect to other devices on the same printed circuit board (PCB) that may require different operating and I/O voltages. With these aspects of implementation easily manipulated using the Altera® Quartus® II software, the Cyclone II device family allows you to use low cost FPGAs while keeping pace with increasing design complexity.
Cyclone II devices support single-ended I/O standards such as LVTTL, LVCMOS, SSTL-2, SSTL-18, HSTL-18, HSTL-15, PCI, and PCI-X to interface with other on-board devices. Single-ended I/O standards are critical when working with advanced memory devices such as double-data rate (DDR and DDR2) SDRAM and QDRII SRAM devices. The table lists the single-ended I/O standards and target performance supported in Cyclone II devices.
From high-speed backplane applications to high-end switch boxes, low-voltage differential signaling (LVDS) is the technology of choice. LVDS is a low-voltage differential signaling standard, allowing higher noise immunity than single-ended I/O technologies. Its low-voltage swing allows for high-speed data transfers, low power consumption, and reduced electromagnetic interference (EMI).
Cyclone II device IOEs contain a bidirectional I/O buffer and three registers for complete embedded bidirectional single data rate transfer. The IOE contains one input register, one output register, and one output enable register. You canuse the input registers for fast setup times and output registers for fast clock-to-output times. Additionally, you can use the output enable (OE) register for fast clock-to-output enable timing. The IOEs are located in I/O blocks around the periphery of the Cyclone II device. There are up to five IOEs per row I/O block and up to four IOEs per column I/O block (column I/O blocks span two columns). The row I/O blocks drive row, column (only C4 interconnects), or direct link interconnects. The column I/O blocks drive column interconnects.
The output buffer for each Cyclone II device I/O pin has a programmable drive strength control for certain I/O standards. The LVTTL, LVCMOS, SSTL-2 class I and II, SSTL-18 class I and II, HSTL-18 class I and II, and HSTL-1.5 class I and II standards have several levels of drive strength that you can control. Using minimum settings provides signal slew rate control to reduce system noise and signal overshoot. The table shows the possible settings for the I/O standards with drive strength control.
PCI Express is rapidly establishing itself as the successor to PCI, It provides higher performance, increased flexibility, and scalability for next-generation systems without increasing costs, all while maintaining software compatibility with existing PCI applications. Now you can easily design high volume, low-cost PCI Express ×1 solutions today with Cyclone II FPGA (EP2C15 or larger). Cyclone® II devices offer hot socketing (also known as hot plug-in, hot insertion, or hot swap) and power sequencing support without the use of any external devices. You can insert or remove a Cyclone II board in a system during system operation without causing undesirable effects to the board or to the running system bus. The hot-socketing feature lessens the board design difficulty when using Cyclone II devices on printed circuit boards (PCBs) that also contain a mixture of 3.3-, 2.5-, 1.8-, and 1.5-V devices. With the Cyclone II hot-socketing feature, you no longer need to ensure a proper power-up sequence for each device on the board.
The I/O pins on Cyclone II devices are grouped together into I/O banks and each bank has a separate power bus. EP2C5 and EP2C8 devices have four I/O banks (see Figure 2–28), while EP2C20 to ECP2C70 devices have eight I/O banks.Each device I/O pin is associated with one I/O bank. To accommodate voltage-referenced I/O standards, each Cyclone II I/O bank has a VREF bus. Each bank in EP2C5, EP2C8, EP2C15, EP2C20, EP2C35, and EP2C50 devices supports two VREF pins and each bank of EP2C70 supports four VREF pins.
Cyclone® II devices have up to four phase-locked loops (PLLs) that provide robust clock management and synthesis for device clock management, external system clock management, and I/O interfaces. Cyclone II PLLs are versatile and can be used as a zero delay buffer, a jitter attenuator, a low skew fan out buffer, or a frequency synthesizer. Cyclone II PLLs support four clock feedback modes: normal mode, zero delay buffer mode, no compensation mode, and source synchronous mode. Cyclone II PLLs do not have support for external feedback mode. All the supported clock feedback modes allow for multiplication and division, phase shifting, and programmable duty cycle.
In the Active Serial configuration scheme, Cyclone II devices are configured using a serial configuration device. These configuration devices are low-cost devices with non-volatile memory that feature a simple, four-pin interface and a small form factor. These features make serial configuration devices an ideal low-cost configuration solution.
The table shows the approximate uncompressed configuration file sizes for Cyclone II devices. To calculate the amount of storage space required for multiple device configurations, add the file size of each device together.
Cyclone II devices include a powerful FPGA feature set optimized for low-cost applications including a wide range of density, memory, embedded multiplier, and packaging options. The low cost and optimized feature set of Cyclone II FPGAs make them ideal solutions for a wide array of automotive, consumer, communications, video processing, test and measurement, and other end-market solutions.
