Translating VCD and VCD+
VHDL Mapping
The following VHDL constructs are mapped for translation from VPD
to VCD. Additional VHDL constructs can be pseudo mapped using
the +morevhdl switch (see
VHDL Mapping). Using the +morevhdl
switch allows you to view the additional VHDL constructs, but there
may be inaccuracies in the pseudo mapped signals, and you cannot
translate a VCD file that uses pseudo mapping back into a VPD file.
