Tutorial Updates

Modeling and simulation of high-speed I/O interfaces with XMODEL

This popular tutorial is now updated with channel crosstalk modeling, voltage-mode transmit equalizer, dither suppression in bang-bang CDRs, and new scripts for BER bathtub, JTRAN, and JTOL simulations.

Tip of the Month

Measuring the coverage of a finite-state machine (FSM) in SystemVerilog

Here is a simple SystemVerilog testbench that can measure the state and transition coverages of your FSM simulation.
