What was the command? Also what your Posit Types setting?

[farhadmerchant]

inside src_bsv/lib

./Gen_Posit_Numeric_Types --posit-width 8 --exp-width 1 --float-width 32

and then from Melodica directory

make POSIT_SIZE=8

@riyarjain On running the above command, the failure is while building FMA. I have cleaned up the Makeile with separate rtl targets and included link_d. Please update before debugging.

@riyarjain
If fixing the type sizing issue with take a while, can you list out a set of good (N, es) combinations which we can put on the README as a guide to users. It does not need to be exhaustive, just representative. We can put in a note that several other (N, es) would work as well, but some may throw up some errors during compilation.

Hello,
Running the below commands, terminal shows me an error of missing "bluesim_kernel_api.h" file.
Is there something I'm missing?
The commands were:
./Gen_Posit_Numeric_Types --posit-width 16 --exp-width 2 --float-width 32 (in lib directory)
make sim POSIT_SIZE=16

/BSV_Additional_Libs/C++/bluesim_main.cxx:47:10: fatal error: bluesim_kernel_api.h: No such file or directory
 #include "bluesim_kernel_api.h"
          ^~~~~~~~~~~~~~~~~~~~~~
compilation terminated.
Makefile:481: recipe for target 'link_adder_d' failed

@MohanaMadhumita
Have you compiled SoftPosit (its a submodule in Melodica)?

[MohanaMadhumita]

Yes, these were run already

madhumita@madhumita-Lenovo-G50-80:~/bsc/Melodica$ git submodule update --init --recursive
madhumita@madhumita-Lenovo-G50-80:~/bsc/Melodica$  cd SoftPosit/build/Linux-x86_64-GCC
madhumita@madhumita-Lenovo-G50-80:~/bsc/Melodica/SoftPosit/build/Linux-x86_64-GCC$ make all
make: Nothing to be done for 'all'.

[farhadmerchant]

what does the following command give you? locate bluesim_kernel_api.h

It's there in the bsc directory.
