edge syntax error while building the RTL simulation platform

[ido-raz]

Hello,

I am trying to build the simulation environment of the PULPissimo and follow the instruction in the README. When running the make command in the 'Building the RTL simulation platform' section I get the following error when the make get to build the 'tbtools' (the same error happened when the make tries to build the 'tb' component): (Also attached print screen)

  Building tbtools/tbtools

Please help. Thanks, Ido

Hello, Any idea what can be the problem? Thanks

Hi @ido-raz sorry for not answering earlier -- this came in during the winter holidays. Can you report the output of the vlog -version command?

[ido-raz]

Hi, Thank you for you response. The output of the command vlog -version is: QuestaSim-64 vlog 10.0c Compiler 2011.07 Jul 21 2011

Is this info gives any clue about the reason to the error? Thanks

Your version of modelsim doesn't support these SystemVerilog features. PULPissimo itself doesn't use most of common_cells though and uses a more conservative set of features from SystemVerilog so I suppose It would be possible to get it running by removing the the offending stuff from common_cells.

I went through all our modelsim/questasim versions and it seems like Questa Sim vsim 10.3e Simulator 2015.02 Feb 23 2015 is at least required for now.
