f4pga-plugins conflicts with Yosys (recent versions)

[amirarjmand93]

Hi @kgugala @hzeller

During making of f4pga-plugins inside the VTR, it seems there is a conflicting between last version of yosys-f4pga-pluginsyosys-f4pga-pluginsyosys-f4pga-plugins and Yosys.

CI Test:
[Run-tests (parmys_reg_strong, 16, -DYOSYS_F4PGA_PLUGINS=ON)]

Command:
make -k CMAKE_PARAMS=-DYOSYS_F4PGA_PLUGINS=ON -j16

• The f4pga-plugins encountered a compilation error due to missing or incorrect member references in the UhdmAst.cc file(in yosys-f4gpa-plugins).

• The errors were related to the structure Yosys::AST::AstNode that did not have the member "multirange_dimensions".

• multirange_dimensions vector member has been replaced( not a simple name replacing) with dimensions vector in recent Yosys updates( v0.39 and later)

• Possibly, The last Yosys version compatible with f4pga-plugins is v0.38 ( I've checked. it still use multirange_dimensions vector)

You can see these changes in v0.32(currently in VTR) and v0.42 of Yosys here:

CI test log file is available from :
F4PGA failing

Short Error:
/root/vtr-verilog-to-routing/vtr-verilog-to-routing/libs/EXTERNAL/yosys-f4pga-plugins/systemverilog-plugin/UhdmAst.cc:824:34: error: 'struct Yosys::AST::AstNode' has no member named 'multirange_dimensions'

My Guess:
In older versions of Yosys (v0.38 and before), the term "multirange_dimensions" was used to store range or dimension-related values, while in new versions of Yosys (v0.39 and onwards), the term "dimensions" is used to store dimension-specific information as tuples or objects. These terms serve different purposes in the code snippets.

It will be my pleasure to see your feedbacks
