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.
