The increased complexity of semiconductor designs that need validating is a problem for simulators, says Pradeep Thiagarajan, principal product manager for custom IC verification, introducing Siemens’ Solido Simulation Suite software (Solido Sim). The suite has three new simulators: Solido SPICE, Solido Fast SPICE and Solido LibSPICE software, together with the company’s AFS platform, ELDO software and Symphony software. Solido Sim ...
Danish company Vind-Vind is developing a turbulence model for the effect of wind on structures in complex environments. It will eventually include the atmosphere high above the volume of interest with wind gusts from different directions. As such, said Vind-Vind CEO Per Jørgensen, wind-tunnel measurements are not good enough and he needed real-world measurements throughout a large volume of atmosphere ...
Distributor RS has added a circuit simulator to its DesignSpark tools. The browser-based tool is rebadged PartQuest Explore from Siemens. “In partnership with Siemen’s PartQuest Explore team, all DesignSpark members, regardless of their subscription option, will have access to the DesignSpark Circuit Simulator tool,” according to RS. It “provides an environment for design, modelling, simulating and analying electronic and mechatronic ...
Oh how long have I been trying to get the switches in LTspice working? Too long, is the answer (please be gentle, I do not have a Spice simulation background 🙂 LTspice has a way to model electromechanical switches, which I have occasionally tried to use to simulate dc-dc converters without all the hassle of setting up mosfets and appropriate ...
Risc-V intellectual property creator SiFive has qualified models for its core portfolio from Oxford-based Imperas Software – as well as signing a distribution deal with Valtrix. Imperas’ models for SiFive processor IP are an instruction accurate programmer’s representation with full functionality including user, privileged, system and debug modes, plus configuration options for Risc-V vector extensions and custom instructions. “The models deliver ...
Cadence is claiming up to 3x transient simulation performance for its latest transistor-level circuit simulator, compared with its previous offering. Called Spectre FX Simulator, it is the next generation of the company’s ‘FastSpice’ branded products, aimed at pre and post-layout verification of large DRAM, flash, SRAM and transistor-level SoC designs. “Design teams can verify functionality and timing for sign-off in a productive manner,” according to ...
Imperas has extended its Risc-V reference model and simulator to cover forthcoming vector instructions and to support coverage-driven verification analysis. Called riscvOVPsim, the enhanced version including a vector test suite is freely available for commercial use from Open Virtual Platforms, and a base version is available free from GitHub. “The upcoming ratification of the Risc-V vector instruction extension offers system designers flexibility ...
Over at www.falstad.com is a circuit simulator with a few ready to run demos. This one is the good old two transistor multivibtrator (pictured), where you can watch voltages change and blobs of current run around – obviously in the opposite direction to any electrons that might be making that current work 🙂 While I can find a way to ...
I am toying with ordering some LEDs and, while checking availability on Digi-Key’s site, came across another free simulator. So I put my flasher circuit into it, and after some fiddling, this is what emerged. Update: better results two days later For drawing the schematic, it is easier and more intuitive than LTspice – on which I tried the same ...
