Solido

Solido from Siemens EDA is a leading variation-aware simulation and library characterization platform for analog, mixed-signal, and custom digital IC design. At advanced process nodes where transistor variability dominates circuit behavior, Solido enables designers to predict yield, validate robustness, and characterize cell libraries with statistical rigor, delivering up to 1000x speedup over brute-force Monte Carlo simulation without sacrificing accuracy.

The platform addresses three critical needs in advanced-node IC design. Solido Variation Designer accelerates Monte Carlo analysis by intelligently sampling the statistical design space, enabling high-sigma yield estimation (6-sigma and beyond) in a fraction of the time required by traditional methods. Solido SPICE Model QA validates foundry SPICE models against silicon data, catching model issues before they propagate into design decisions. Solido Characterization Suite automates the characterization of standard cell, memory, and I/O libraries for timing, power, and noise, generating Liberty (.lib), NLDM, CCS, and ECSM models that digital implementation flows consume.

Solido is essential for analog/mixed-signal teams designing PLLs, ADCs, DACs, SerDes, and power management ICs where process variation directly impacts yield and performance. Library teams at foundries and fabless companies rely on Solido Characterization Suite to produce the timing and power models that enable digital synthesis and place-and-route flows.

GSAS Micro Systems provides Solido licensing and technical support for IC design teams across India, with guidance on variation-aware methodology adoption, characterization flow setup, and integration with existing analog simulation environments.
