Stimulus From VCD Files Using the $vcdin() System Task

008_vcd_in : Stimulus From VCD Files Using the $vcdin() System Task

Minimum Required Versions: SILOS 4.12.1.C

Example 008_vcd_in is a drink vending machine implemented as a Verilog gate level design. Included in this example are the Gateway schematic for the circuit as well as the testbench and library files are vcd_input.lib and primitives.v

Use $vcdin() System Task to Read Circuit Stimulus from VCD File

  • Start SILOS, open the project file "vcdin.spjx" and click "Go" to run the simulation.
  • The output from the simulation is written to output window.
  • Observe the message "Read circuit stimulus using $vcdin()" in the output window.
  • Double click on the message and observe the initial block containing the call to $vcdin().
