Fix include path to tool-specific DPI libs
This pull-request is a fix for an issue reported #1656.
The Makefile target dpi_dasm
requires a path to the simulator tool-specific DPI libraries. This is both tool (xrun, vcs, etc.) and installation dependent, so it needs to be placed in mk/uvmt/<simulator>.mk
. These simulator tool-specific Makefiles are required to set variable DPI_INCLUDE
. It was not set properly VCS.
This PR sets DPI_INCLUDE
for VCS and DSIM and adds a comment to XRUN and VSIM simulator makefiles.
