Page 16: Functional Simulation
This section contains instructions for running a timing simulation of the CAN core using either VHDL or Verilog. A timing simulation model is generated when the core is run through the Xilinx tools using the implement script. It is a requirement that the core is implemented before attempting to run timing simulation. -
