Syntax

pID = pingHdlSim(timeout)
pID = pingHdlSim(timeout,portnumber)
pID = pingHdlSim(timeout,portnumber,hostname)

Description

pID = pingHdlSim(timeout) attempts to connect to the HDL simulator using a shared connection. The function blocks cosimulation until the HDL server loads or the specified timeout occurs. pingHdlSim returns the process ID pID of the HDL simulator or -1 if a timeout occurs. When you automate a cosimulation, use this function to determine if the HDL server is loaded before your script continues the simulation.

example

pID = pingHdlSim(timeout,portnumber) attempts to connect to the local host on the port portnumber.

example

pID = pingHdlSim(timeout,portnumber,hostname) attempts to connect to the host hostname on port portnumber.

The following function call blocks further cosimulation until the HDL server loads or 30 seconds pass.

pingHdlSim(30)

If the server loads within 30 seconds, pingHdlSim returns the process ID. Otherwise, pingHdlSim returns -1.

The following function call blocks further cosimulation on port 5678 until the HDL server loads or 20 seconds pass.

pingHdlSim(20,'5678')

The following function call blocks further cosimulation on port 5678 on host name msuser until the HDL server loads or 20 seconds pass:

pingHdlSim(20,'5678','msuser')
