SMASH Mixed-Signal Simulator

Description

SMASH is a seamless IC-PCB mixed-signal simulator enabling the development and verification of analog and mixed-signal Silicon IPs and Integrated Circuits (IC) as well as the optimization of application schematics thanks to its unique multi-domain capabilities.

With the mixed-signal simulator SMASH, designers benefit from innovative features which enable efficient and fast detection of design defects with a fine control for tuning the speed accuracy trade-offs.

These features address the request from designers to rely on a simulator which can truly help them improve their design productivity for as faster and safer time-to-fab. Indeed, the analysis of the time spent by engineers to complete their designs shows that most of their valuable time can be saved with a simulator offering appropriate design bug detection features as well as debugging features.

SMASH is the mixed-signal simulator of choice for designers eager to improve their productivity!

Presentation Sheet
SMASH 7.6
SMASH 7.6.0 mixed-signal simulator significantly speeds up OP/DC and transient analyses of analog and mixed designs in advanced nodes by a gain between x2 and x6. These major speed-up gains have been possible thanks to new methods and algorithms without losing simulation accuracy, as merge of identical SPICE instances, improve evaluation of MOS transistors, RC reduction methods and new Solver. All these features allow SMASH to be as fast or even to overtake the major fastest golden spice simulators, while ensuring accuracy of a single solver SPICE simulator. SMASH is now supporting SystemVerilog language for RTL synthesizable simulations, thanks to the integration of Verilator. Verilator is open source Verilog/SystemVerilog simulator. Verilator converts Verilog HDL modules to C++ models which are simulated by SMASH.

SMASH 7.5
SMASH 7.5.0 mixed-signal simulator speeds up transient analysis of leading-edge analog and mixed designs by up to 1.5X compared to previous release. Moreover, with SMASH 7.5.0, convergence of OP and DC analyses has been strongly improved and speed up by 10X or more, especially for mixed-signal circuits. Now SMASH 7.5.0 supports TSMC Model Interface (TMI) aging flow to simulate Hot Carrier injection (HCI) and Bias Temperature Instability (BTI) effects in design for reliability validations.

SMASH 7.4
With SMASH 7.4, for circuits with thousands of MOS devices in advanced process nodes and/or post-extractionRC, designer productivity has been enhanced by improving and accelerating transient analysis by a factor x2 and more without losing simulations accuracy. Moreover, for checking the stability of closed loop systems, SMASH 7.4 provides a new method “Zeq” to enable draw of any voltage node.

SMASH 7.2 - New custom static electrical rules checking
SMASH 7.2 provides new API functionalities to scan analog circuit across DEVICE connections and to verify your own custom Static Electrical Rules Checking. An example part of the installation kit enables to detect automatically and quickly all MOS transistors with gates directly connected to supply sources, without launching any simulation.

SMASH 7.1 - Optimize monte carlo analysis
Accelerating Monte Carlo Analysis is crucial because designs in advanced process-node have much larger variation and need to run thousands or even millions of statistical simulations. Thus, with SMASH 7.1, for circuits with thousands of MOS devices, Monte Carlo analysis has been sped-up by accelerating loading phase of each run by a factor of up to x3.Moreover, with SMASH 7.5.0, convergence of OP and DC analyses has been strongly improved and speed up by 10X or more, especially for mixed-signal circuits. Now SMASH 7.5.0 supports TSMC Model Interface (TMI) aging flow to simulate Hot Carrier injection (HCI) and Bias Temperature Instability (BTI) effects in design for reliability validations.

SMASH 7.0 - 64-bit native application
Starting from now, all our EDA solutions will only be available in 64-bit versions for x86_64 platforms with Microsoft Windows Vista/7/8/10 or with RedHat Enterprise Linux 6 (RHEL6) and compatible Linux distributions. Native 64-bit applications allow to overcome the limitations of 32-bit versions, such as loading large designs and simplifying installations on a 64-bit Linux OS.
