Solido – Variation Analysis and Design Software for Custom ICs

Solido – Variation Analysis and Design Software for Custom ICs
by Daniel Payne on 08-15-2011 at 7:11 pm

Introduction
When I designed DRAM chips at Intel I wanted to simulate at the worst case process corners to help make my design as robust as possible in order to improve yields. My manager knew what the worst case corners were based on years of prior experience, so that’s what I used for my circuit simulations.… Read More

Intro
On Monday evening I talked with Linda Fosler, Director of marketing for the DSM Division at Mentor about what’s new at DAC this year in circuit simulation and IC layout tools.

Notes
IC Station – old name for IC layout tools

Eldo – Eldo Classic- Cell characterization
– ST is the early customer and teaching customer,… Read More


A New Hierarchical 3D Field Solver

A New Hierarchical 3D Field Solver
by Daniel Payne on 05-19-2011 at 2:04 pm

Introduction
3D field solvers produce the most accurate netlists of RC values of your IC layout that can then be used in SPICE circuit simulators however most of these solvers produce a flat netlist which tends to simulate rather slowly. Thankfully several years ago the first hierarchical SPICE tools were offered by Nassda (HSIMRead More


The Ultimate SPICE Circuit Simulator

The Ultimate SPICE Circuit Simulator
by Daniel Payne on 01-03-2011 at 1:19 pm


I love SPICE and Fast SPICE circuit simulators, so here’s my feature list for the ultimate SPICE circuit simulator:

[LIST=1]

  • Input netlists – HSPICE, Spectre, ELDO
  • Multi-core support – parse and simulate fast and accurate
  • LRC Reduction – built-in LRC reduction with a few knobs to control accuracy
  • Tuning
  • Read More
