Depending on your current focus (browsing the design, writing testbench code, debugging) you only want to load in DVT the relevant code |
rtl.build contains all directives needed to compile the design
testbench.build contains all the directives needed to compile the verification environment
default.build includes both the rtl.build and testbench.build |
Quickly switch between synthesizable and non-synthesizable version of the design hierarchy |
default.build contains all directives needed to compile all the code
synth.build contains +dvt_preprocess_translate_pragmas+synthesis and a -f directive to include default.build |
You switch often between several versions of the same code base. The paths to the few different files are controlled by the $VERSION environment variable. |
compile.f contains directives needed to compile all the code
version1.build contains +dvt_setenv+VERSION=1 and a -f directive to include compile.f
version2.build contains +dvt_setenv+VERSION=2 and a -f directive to include compile.f

You want to change the active build before launching DVT, as designers compile just the RTL by rtl.build, while others all.build. |
Change the build name in .dvt/build.config.xml before launching DVT, for example by a wrapper script run_dvt.sh -rtl. |
