add svf-file generation

[frantony]

@olofk Most of the time I use openocd to burn Altera's FPGA (e.g. I use Raspberry Pi for burning FPGA and can't run Quartus on it). Can we add svf-file generation feature to fusesoc? Just now I use this patch:

I think that the patch is not perfect (e.g. hardcoding -q 2MHz -g 3.3 is a bad solution, I have to move this options to configuration file).

Any suggestions?

Hi,

That's one way to solve your issue, but I'm always hesitating a bit to add more options directly into FuseSoC and prefer to keep these things in tcl files whenever possible. For example, I have a similar situation where I need to generate an rbf file with quartus. To do this, I add set_global_assignment -name GENERATE_RBF_FILE ON to one of the tcl files that is loaded from FuseSoC (to load a tcl file, add it to a fileset or create a new one, and set usage=quartus and file_type=tclSource). I haven't checked, but there is likely some way to do this. Another option would be to create a script that runs quartus_cpf and add it to the core file as a post_impl_script in the [scripts] section

Thank you for your suggestion!

I have found GENERATE_CONFIG_SVF_FILE and GENERATE_SVF_FILE options in the Quartus Prime Settings File Reference Manual. I have enabled these options and svf-files were succesfully generated without any changes in the fusesoc codes.
