GRID Simulation Technology today announced SimCHECK, a qualification tool for verifying the accuracy of the Electromigration and IR drop (EMIR) simulation results of complex networks such as power grids, signal and clock nets, and silicon substrates in IP Blocks, and SoCs.
Today's generation of low power SoCs manufactured at advanced process nodes are challenged by competing and often conflicting electrical design requirements; high computational functions, low power operating budgets, and increasingly higher frequencies. ICs designed to meet these requirements are susceptible to transient noise effects due to the high density of the transistors and miles of interconnect wiring. Unseen variations in IR voltage drop can have dramatic impacts on product yields in terms of leakage, performance, and reliability. Qualified, SPICE accurate, EMIR analysis is now a critical mandate for verification and sign-off of functionality, timing, and reliability of these designs.
