Generation of RippleFPGA Input FIles from Vivado

Hi!

RippleFPGA is so comprehensive that I wonder whether we can export some designs from Vivado and test them with it. I notice that Vivado can export DCP file but RippleFPGA also requires files with suffixes like, .aux, .scl, .pl and so on, which I failed to find in the documentation of Vivado.

Thanks in advance for your help! ^_^

Best regards,

fail to build

Hi, I am trying to build Ripple, but there is an error "gd.h: No such file or directory" when I make mode=release_mt.

Am I missing any steps?
Help me! Thanks!

Can't make file with the release_mt tag

(I have modified src/Makefile to match the versions of gcc and boost.)
I have faced issues when it is fetching the gd.h file, which I believe is some packages used for debug mode. I could have solved the issue by deleting all the codes related to draw.h, but that would waste me plenty of time.

Below is the error message:

g++ -std=c++11  -I. -I../../boost_1_71_0 -O3 -DNDEBUG -static -Wall -MMD -MP -o main.o -c main.cpp

make debug build

Dear sir,

I compiled your source code with the command "make mode=debug", but it failed and the log shows "xxxx can not be used when making a PIE object,recompile with -fPIC".

I searched on internet, and i found by adding compile option "-no_pie" to Makefile, the issue can be fixed.
Does it ever happened to you?

Thanks,
Liran
