As such, modern day designers often simplify ‘RTL synthesis’
to just ‘synthesis’, however this is not the whole story. As designs
have continued to get more complex, there has been a push to ever
increasing behavioral synthesis however there is not the same sup-
port from the EDA industry for behavioral synthesis software.
VHDL supported in RTL synthesis
While VHDL is standardized, synthesis is not, and as such the
VHDL that can be synthesized is a subset of the complete VHDL
language. Another common problem for designers is the fact that
different synthesis software packages will give different output
results for the same input VHDL, even to the extent ...
