Jeda Hls Hlv Success Story V4
This document discusses accelerating verification of high-level synthesis (HLS) blocks using the JEDA HLV Tool Suite. It provides a new verification flow that allows identifying untested and dead code earlier at the SystemC/C-level, improving testbenches faster using faster C models. The JEDA tools provide hardware-aware coverage measurement at the SystemC level that reliably carries over to the RTL level, allowing for both fast time to RTL and efficient verification. This enables achieving true faster time to market by moving verification automation to the high level.
An Approach to Overcome Modeling Inaccuracies for Performance Simulation Sig...
RNM is finding prominence in functional verification signoff, However there is clear modeling gap when it comes to performance simulation of high-speed SerDes. Sometimes the pre-silicon simulation results show passing results with respect to Jitter tolerance (JTOL) specification which may not match the actual silicon validation results. These performance issues manifest due to inaccuracies of model where it may not comprehend the actual circuit behavior. There is no clear methodology to overcome these model gaps for performance simulation signoff.
This paper discusses in detail the techniques used to accurately model and verify high-speed SerDes systems for performance simulation.
Unified methodology for effective correlation of soc power
Unified Framework across Pre and Post Silicon platforms for accurate power estimation and measurements
Qualifying a high performance memory subsysten for Functional Safety
Addressing the Challenges of Safety verification for LPDDR4.
✓Avoid traditional approach of starting functional safety after functional verification : Iterative and expensive development phase
1. Functional Safety Need to be Architected and not added later.
2. Safety Analysis must start prior to implementation. ‘Design for safety/verification’
3. Reuse & Synergize : Nominal and Functional Safety Verification.
✓Fault optimization with formal and other techniques is necessary to overcome challenges with scaling simulation and analysis.
✓Integrated push button fault simulation flow is need of hour and saves verification engineers time.
✓Analog defect modelling and coverage can be performed based on IEEE P2427.
Overcoming challenges of_verifying complex mixed signal designs
Efficient and Innovative Digital Mixed-Signal (DMS) verification methodology is required to enable effective verification of RX path of SERDES. This presentation describes the usage of Real value models and Capture -Verify approach to verify complex high speed mixed signal design.
Real value models are the backbone of DMS methodology. Real value models are created for all critical modules in Receive path like Equalizer and Sampler and its associated peripheral modules. It is critical to make sure created models are functionally equivalent to respective designs. This is achieved by verifying each created model with respective designs for all functional modes. While the Real Value models are effective in meeting overcoming the simulation performance bottleneck by achieving 10x faster simulation time; the Nonlinearity factors of the front-end design are not represented accurately in discrete domain real value models for next generation of SerDes Design at very high data rate.
To overcome this problem, a novel approach called ‘capture and verify’ is used for verifying the jitter tolerance and eye parameters. In this approach, waveforms from spice level verification of Equalizer for different functional modes are captured and stored. These stored waveforms are used to generate run time table-based models to accurately represent the analog modules. These run time models are used in top-level simulations along with real value models thereby achieving required goal of simulation performance without compromising on accuracy of results.
The complete Design Verification (DV) environment is developed using UVM-e Methodology. Verification environment contains model for transmitter with all de-emphasis settings along with protocol compliant channels with multiple attenuations. DV infrastructure has hooks to plug-in required channel models to verify SERDES. This verification environment is also capable of verifying the clock data recovery (CDR) path of the design using protocol compliant jitter and Spread-Spectrum Clocking (SSC) stimulus.
The real value modelling bridges the gap between the performance requirements of the simulation and accuracy limitations of design. A significant speed-up in simulation performance is achieved (almost 10X in this case) by replacing with functionally equivalent real value models for mixed signal designs. Usage of Capture and Verify methodology with spice simulation waveforms for critical blocks ensures non-linearity of the next generation high speed SerDes design is well captured in simulations provide complete comprehensive solution for high speed mixed signal designs.

You name it, we analyze it
With the ever increasing number of networking protocols, it can be difficult for vendors, integrators, and end-users to determine how well different products and systems perform in real-world networking situations. Each protocol has their own method of defining traffic streams and message structures. Packet analyzers, like Wireshark, have been developed to interpret individual network packets and can perform rudimentary analysis of traffic streams for well-known packet types. Analyzing industrial protocols usually requires much more massaging of the data and in many cases requires a user to do much of the work by hand. This session will present a method to break-down industrial traffic streams into the core components necessary to analyze their performance. By identifying a few key fields in each protocol, a user can define their own method to identify individual traffic streams and analyze their performance.

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODEL
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.

The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.

TIME DIVISION MULTIPLEXING TECHNIQUE FOR COMMUNICATION SYSTEM
Time Division Multiplexing (TDM) is a method of transmitting multiple signals over a single communication channel by dividing the signal into many segments, each having a very short duration of time. These time slots are then allocated to different data streams, allowing multiple signals to share the same transmission medium efficiently. TDM is widely used in telecommunications and data communication systems.
### How TDM Works
1. **Time Slots Allocation**: The core principle of TDM is to assign distinct time slots to each signal. During each time slot, the respective signal is transmitted, and then the process repeats cyclically. For example, if there are four signals to be transmitted, the TDM cycle will divide time into four slots, each assigned to one signal.
2. **Synchronization**: Synchronization is crucial in TDM systems to ensure that the signals are correctly aligned with their respective time slots. Both the transmitter and receiver must be synchronized to avoid any overlap or loss of data. This synchronization is typically maintained by a clock signal that ensures time slots are accurately aligned.
3. **Frame Structure**: TDM data is organized into frames, where each frame consists of a set of time slots. Each frame is repeated at regular intervals, ensuring continuous transmission of data streams. The frame structure helps in managing the data streams and maintaining the synchronization between the transmitter and receiver.
4. **Multiplexer and Demultiplexer**: At the transmitting end, a multiplexer combines multiple input signals into a single composite signal by assigning each signal to a specific time slot. At the receiving end, a demultiplexer separates the composite signal back into individual signals based on their respective time slots.
### Types of TDM
1. **Synchronous TDM**: In synchronous TDM, time slots are pre-assigned to each signal, regardless of whether the signal has data to transmit or not. This can lead to inefficiencies if some time slots remain empty due to the absence of data.
2. **Asynchronous TDM (or Statistical TDM)**: Asynchronous TDM addresses the inefficiencies of synchronous TDM by allocating time slots dynamically based on the presence of data. Time slots are assigned only when there is data to transmit, which optimizes the use of the communication channel.
### Applications of TDM
- **Telecommunications**: TDM is extensively used in telecommunication systems, such as in T1 and E1 lines, where multiple telephone calls are transmitted over a single line by assigning each call to a specific time slot.
- **Digital Audio and Video Broadcasting**: TDM is used in broadcasting systems to transmit multiple audio or video streams over a single channel, ensuring efficient use of bandwidth.
- **Computer Networks**: TDM is used in network protocols and systems to manage the transmission of data from multiple sources over a single network medium.
### Advantages of TDM
- **Efficient Use of Bandwidth**: TDM all
