I'm working on a high-performance design. With the help of KKP in https://www.avrfreaks.net/index.p... , I found the IBIS models for the AVR microcontrollers.
I'm leaning towards purchasing LineSim from Mentor Graphics to simulate the PCB traces and signals using the IBIS models. While LineSim seems quite competent and seems like a reasonable value, its price is considerable.
Does anyone have a recommendation for a signal simulator using IBIS models, probably less featured, but more affordable than LineSim?
