4.22 Use of External Programs

The DVT compiler may run external programs in order to determine various locations used in the build configuration. For example, 'irun -location -nolog -nohistory' is executed in order to compute the location of the CDN UVM library when in the ius.irun compatibility mode.

The default timeout is 20 seconds. To specify a different timeout, in the terminal where you run DVT set the DVT_EXTERNAL_PROGRAM_TIMEOUT environment variable with the new timeout in milliseconds. For example to set a 40 seconds timeout:

setenv DVT_EXTERNAL_PROGRAM_TIMEOUT 40000

Set 0 to disable the timeout.
