A customer wants to analyze/elaborate
From Verific Design Automation FAQ
Q: A customer wants to analyze/elaborate different VHDL flavors (1993 and 2008). They want to process the 93 files first and then the 08. As each flavor has its own IEEE library set, do you have any suggestion on how to handle this scenario?
A: Please load the 2008 version of the IEEE library distributed by Verific and then analyze the 1993 and 2008 design files in their proper dialect. Verific will internally adjust the packages and both the designs should compile without any errors. For example:
setvhdllibrarypath -default verific_source/vhdl_packages/vdbs_2008 analyze test93.vhdl analyze -vhdl_2008 test2008.vhdl
