Problem Title:
XNF file created by EDIF2XNF contains high-level symbols instead of
primitives



Problem Description:
If the value of the $LCA environment variable is incorrectly set OR the $LCA
variable is not referenced in the mgc_location_map file, ENWrite (Mentor's
EDIF netlist writer) will be unable to traverse the hierarchy of XIlinx
macros, and will instead describe them as "black boxes" (i.e., primitives)
rather than write out their full schematic descriptions.


Solution 1:

This is easily fixed by setting $LCA to the pathname of the Mentor-interface
software (DS344).
