I would like to pass, from the TCL file that is commanding the Diamond tool of Lattice, some options to the Synplify synthesis tool.

E.g.: It is possible to set a value of the VHDL generic at toplevel in the GUI. https://www.doulos.com/knowhow/fpga/Setting_Generics_Parameters_for_Synthesis/

But when saving this project in TCL (save_script test.tcl), this option is not exported to TCL.

Adding the Synplify TCL code in the Lattice TCL file isn't helping.

set_option -hdl_param -set BUILD_VERSION {x"01"}

pnmainc diamond.tcl
invalid command name "set_option"
    while executing
"set_option -hdl_param -set BUILD_VERSION x"01""
    (file "diamond.tcl" line 3)

And the manual not the help in Lattice/TCL isn't revealing anything.

I would like to avoid having another TCL file just for Synplify in my repo.

    \$\begingroup\$ Are you using LSE or Synplify? I'm avoiding a direct call to pnmainc. So I'm calling synthesis -f <optionfile> directly. \$\endgroup\$

  • \$\begingroup\$ @paebbels I'm using Synplify. But I should check with the owner of the code why :-). 'synthesis.exe' is LSE, I assume. \$\endgroup\$

(I still think it's stupid I can't post that as a comment before 50rep)

Try with the following syntax:

hdl_param -set BUILD_VERSION x"01"
