ViaWizards help you design mixed-signal circuits suitable for ASIC integration without having you having to be a full-custom designer. ViaDesigner is mixed-signal IC design software that runs in the cloud at www.ViaDesigner.com. The ViaDesigner app comes with a library of ViaWizards useful for creating circuits like: amplifiers, programmable gain stages, instrumentation amplifiers, fully differential op-amps, log amps, transimpedance amplifiers, analog muxes, linear regulators, buck regulators, SAR analog to digital converters, sigma delta ADCs, current steering DACs, voltage DACs, bandgap voltage references, bias generators, high voltage circuits,...(more). Explore ViaDesigner.com and get started developing mixed-signal ICs yourself. You can get to prototype via configured ASICs for ZERO NRE.

    • 2. 2www.ViaDesigner.com A ViaWizard is a mixed-signal circuit generator that you use to kick start your IC development. {No full-custom IC design know-how required}
    • 3. www.ViaDesigner.com 3 ViaWizards • Library of mixed-signal circuit generators • Simplify & speed-up the design of circuits • Incorporate expert IC design know-how • Generate high-level VHDL-AMS models for high-fidelity and fast simulations • Synthesized into via configurable soft-IP • Act as a product selector guide • Provide feedback about good design practices
    • 4. www.ViaDesigner.com 4 An Example: Design a Low Pass Filter Design parameters & process 1. Continuous or Switched Capacitor 2. Passband, Stopband Ripple 3. Corner Frequency 4. Stopband Frequency & Attenuation 5. Select Filter Approximation 6. Compute Component Values
    • 5. 5www.ViaDesigner.com Manual schematic capture of a switched capacitor lowpass filter
    • 6. www.ViaDesigner.com 6 in out clk ib avdd avss ViaWizard design of a lowpass filter Switched Capacitor Low-Pass Filter Design parameters & process 1. Place wizard on schematic 2. Configure the wizard via the parameter form 3. Press [OK] to generate a VHDL-AMS model 1 2 3
    • 7. 7www.ViaDesigner.com Enter design inputs in the Filter Wizard form to configure the filter characteristics.
    • 8. 8www.ViaDesigner.com The Filter Wizard creates a VHDL-AMS model of the filter ready for simulation.
