3.7 Multiple .build Files
You can have multiple
build files inside the .dvt directory and tell DVT which one to use for compilation by using the
"DVT: Set Current Build Configuration..." command or by clicking on the status bar item that shows the current build name.
|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 the 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".
