Setting up the FSDB reader
The article will help you to configure and set-up the FSDB readers native extension.
The FSDB reader uses a native extension, meaning that it calls a native application (converter) to open and read data from the fsdb file. Find more about native extensions in the manual.
This native extension requires a library from a 3rd party tool installation (FsdbReader) that usually comes with the Verdi tool chain (Synopsys).
Setting up the native extension
Go to Preferences->impulse->Native Extensions->Fsdb Native.
- Please check if your system has the required GNU compatible toolchain installed (g++,make)
- Use the folder selection button of the first entry to select the include path of FsdbReader.
- Now select (2nd field) the library path that fits to your system.
- Press Make

Editing the native extension
If you press Edit Extension, impulse opens an editor with the converter sources.
This enables experienced users to enhance the readers native extension or to explore the fsdb content in a different manner. We are looking forward to get your feedback!
