The xvhdl and xvlog commands parse VHDL and Verilog files, respectively. Descriptions
for each option are available in Table 5-2, page 102.
This command parses the VHDL source file(s) and stores the parsed dump into a HDL library
on disk.
***** xelab
xelab
The xelab command, for given top-level units, does the following:
• Loads children design units using language binding rules or the L <library>
command line specified HDL libraries
• Performs a static elaboration of the design (sets parameters, generics, puts generate
statements into effect, and so forth)
• Generates executable code
• Links the generated executable code with the simulation kernel library to create an
executable simulation snapshot
You then use the produced executable simulation snapshot name as an option to the xsim
command along with other options to effect HDL simulation
