Xcelium simulator is not running when vhpi application is loaded.

John Davis

I am able to load and execute a vhpi application that can read the vhdl hierarchy, and can put and get values.

The problem I am having is that when I put a value on to. say an input,  it does not propagate even though I have used the vhpiDepositPropagate or vhpiForcePropagate flags.
I know I am setting the value because I can read it back via vhpi_get_value() and because at the end of my application the simulator does run and the last values I applied are used.

It seems like my application is running but the simulator is not.  The other reason I suspect this is because if I call vhpi_control(vhpiReset) I get a warning:

WARNING: VHPI NOTRUN
vhpi_control with vhpiReset called while simulator is not running.
xcelium> run
xmsim: *W,RNQUIE: Simulation is complete.
xcelium> exit

I feel I am missing something very basic.

  • Here is an example of the how I invoke the simulator.

    The function is loaded via -vhpiload.
    It seems to load and run and then after it exits the simulator runs.

    Is there some other way I should be calling a function to drive the simulation?
