A UVM Testbench for Exploring Design Margins of Analog/Mixed-Signal Systems: A PCI-Express Receiver Detection Circuit Example

This testbench finds the worst-case response of an analog circuit over a continuous-valued parameter space by combining a reactive stimulus technique with a Bayesian optimization algorithm. Learn more

Q&A of the Month

Can XMODEL simulate the time-domain reflectometry (TDR) response of a transmission line circuit?

Yes, simply model a TDR instrument that applies a 1V step and simulate the reflected waveform. Learn more
