SMASH 5.7 Empowered Mixity

 

SMASH 5.7 is loaded with innovative features which contribute to increasing the productivity of logic, analog and mixed signal designers. With good estimates of power consumption in logic circuits, designers can make an educated selection of low-power architectures and of logic blocks.

Now, for the first time, a simulator popularizes the setup of parameters to obtain the appropriate speed/accuracy tradeoff for a given Virtual Test.

 

Key enhancements

  • Graphic User Interface for Trading-off Accuracy and Rapidity (GUITAR)
  • Logic power consumption estimation (SCROOGE)
  • Extended compliance with Verilog-AMS and VHDL-AMS standards
  • Unleashed SPICE and VHDL-AMS mixity allowing any hierarchical instantiations
  • Enhanced API including script capabilities using Tcl
  • Automatically documented SPICE device models
  • Increased logic simulation speed (up to a factor of 2)

Highlights on new capabilities

Addressing the issue of simulation parameter setup, GUITAR provides an innovative graphical approach to setting the parameters thereby increasing designer awareness to simulator settings and their correlated effects. With the capability to select the appropriate trade-off designers shall detect design bugs faster prior to extract characteristics at the needed accuracy with the highest possible speed:

  • The SCROOGE add-on estimates logic power consumption of RTL netlists using standard cell libraries associated with Liberty technology library files.
  • Already sporting the best VHDL-AMS compliance on the market, SMASH 5.7 goes further and provides enhanced HDL-AMS compliance, while offering full hierarchical mixing of SPICE with VHDL-AMS.
  • Any arrangement of SPICE sub-circuits and VHDL-AMS architectures can be mixed in the hierarchy with improved reporting of AMS node values both in the operating point file and in the simulation results.
  • Scripting and extending SMASH is enhanced with Tcl scripting capabilities and an extended Application Programming Interface (API).
