Running simulation with GHDL and Vivado libraries

[TylerD83]

Hi,

in my project, I included unisim and unimacro libraries from Vivado. When I start a simulation I get following types of error messages:

Error: C:/Xilinx/Vivado/2023.1/data/vhdl/src/unisims/retarget/RAMB18.vhd:23:10: use of synopsys pack age "std_logic_signed" needs the -fsynopsys option Error: ../../src/vital2000/timing_p.vhdl:152:14:note: (you can use -frelaxed to turn this error into a warning)

As a workaround I updated line 216 of VendorScripts_GHDL.tcl: set LocalElaborateOptions [concat --std=${VhdlShortVersion} --syn-binding -fsynopsys -frelaxed {*}${ExtendedElaborateOptions} {*}${CoSimElaborateOptions} --work=${LibraryName} --workdir=${GHDL_WORKING_LIBRARY_PATH} ${VHDL_RESOURCE_LIBRARY_PATHS} {*}${args}]

I don't think hard-coded options are the right solution in this case. Any proposal how to solve it right?

See the Script_user_guide.pdf in the Documentation repository. The should be a SetExtendedElaborateOptions that you can put in your LocalScriptDefaults.tcl.

I am on travel today, but that should point you in the right direction.

In LocalScriptDefaults.tcl you can have conditionals that do things only for one simulator - such as ghdl

Thanks alot. This helped. 👍
