Running skill function before simulation to prevent its start

aakhavan

I'd like to set up my environment to run a skill function just before a simulation starts to check system load. If the load is too high, it will display a message and prevent the simulation from running. I need to support both ADE-L and ADE-XL. What's the best way to do this?

From what I've found in the documentation, I can add a pre-simulation callback in ADE-XL using the axl* functions and signals/triggers. However, it does not appear that the callback can prevent the simulation from running.

For ADE-L, I've not been able to find a similar pre-sim callback. I could either overwrite all of the toolbar buttons and menu items, or overwrite the run functions. It seems that the UI elements are all re-generated and the callbacks for them changed every time the simulator changes, which poses a problem.

I can overwrite all of the run simulation functions, but I'd have to do so for every simulator (assuming they don't get re-defined on simulator changes).

    For ADE XL (and Explorer and Assembler) you'd use a preRun trigger (specified with axlSessionConnect). In the preRun trigger, you need to set this env var - it's not based on the return value of the preRun trigger (unfortunately) - so you need to use this as a semaphore to indicate that you want to halt the run:

    ;----------------------------------------------------------------
    ; This is a semaphore to indicate that the simulation should not
    ; proceed
    ;----------------------------------------------------------------
    envSetVal("adexl.simulation" "haltCurrentRunAfterPreRunTrigger" 'boolean t)

    For ADE L, you'd change the flowchart step for (say) asiStartSimulator:

    procedure(CCFstartSimPreFunc(session)
      let(((status t))
        when(getd('CCFexistingSpectrePreFunc)
          status=CCFexistingSpectrePreFunc(session)
        )
        when(status
          ; do your determination on whether to proceed here and return t (to start) or nil (to not start)
          ; the line below is just to allow me to experiment with setting CCFRETURNVALUE globally to t or nil to 
          ; control whether sim starts or not
          if(boundp('CCFRETURNVALUE) then CCFRETURNVALUE else t)
        )
      )
    )

    tool=asiGetTool('spectre)
    flow=asiGetFlowchart(tool)
    step=asiGetFlowchartStep(flow 'asiStartSimulator)
    unless(step->preFunc=='CCFstartSimPreFunc
      putd('CCFexistingSpectrePreFunc step->preFunc)
    )
    asiChangeFlowchartStep(flow ?name 'asiStartSimulator ?preFunc 'CCFstartSimPreFunc)

    Hope that helps!
