VCS -top option is ambiguous #771
Description
According to the documentation, it is necessary for specifying the top-level configuration or module of the design (i.e. the testbench module). Unfortunately, TestDriver in Chipyard appears to be compiled by VCS, and thus specifying -top TestDriver leads to a module collision:
Error-[TMENF-ILL] Top Module/Entity not found
Top module/entity/config "TestDriver" is not found in the following library
list.
Liblist: work
Error-[IRMINTM] Illegal module instantiations
Illegal to have recursive module instantiations.
No Top Modules Defined
There should be at least one top module that is not instantiated by any
other module.
ucb-bar/hammer-synopsys-plugins#34 made -top optional as a workaround for now.
