Setting up the WLF reader
The article will help you to configure and set-up the WLF readers native extension.
The WLF reader uses a native extension, meaning that it calls a native application (converter) to open and read data from the WLF file. Find more about native extensions in the manual.
This native extension requires a library from a 3rd party tool installation (wlfapi) that usually comes with the ModelSim tool chain (Mentor Graphics).
Setting up the native extension
Go to Preferences->impulse->Native Extensions->WLF 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 wlfapi.
- Now select (2nd field) the library path that fits to your system.
- Press Make
mkdir -p win32-x86 gcc main.c ../flux.c ../lz4.c ../fastlz.c -I .. -I . -I 'C:\Program Files\altera\13.0\modelsim_ase\include' -L 'C:\Program Files\altera\13.0\modelsim_ase\win32aloem' -D FLX_CONTROL -D FLX_COMPRESS -D FLX_STDIO -D FLX_ITEM_EXTENSION="flxbyte signalType;flxuint signalScale;void*varId;void*value;" -Wno-pointer-to-int-cast -Wno-int-to-pointer-cast -g -lwlf -o win32-x86/wlf.exe
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 WLF content in a different manner. We are looking forward to get your feedback!
