How to debug VerilogA compilation when code seems to check clean but simulation aborts when compiling ?

Hello I have a verilogA module using multi-terminal ports and where I want to use for loops to assign all currents. I took care to use genvars, and I don't get any syntax error during the check after saving the verilogA view. However during simulation, spectre is aborting (very laconically, even if I use option +debug).

** Below the header of my module :

  module qnrmesh2d(majport,minport);
   
   // Majority carriers terminals  
   inout [1:`QNRMESH2D_NPORTS] majport;
   electrical [1:`QNRMESH2D_NPORTS] majport;

   // Minority carriers terminals  
   inout [1:`QNRMESH2D_NPORTS] minport;
   electrical [1:`QNRMESH2D_NPORTS] minport;

 ...

**  Below the declarations of my genvars :

    genvar    thisPort, otherPort, refPort; 

**  Below a typical set of loops

     // Trick to define the reference port
      for (refPort = `QNRMESH2D_NPORTS; refPort == `QNRMESH2D_NPORTS; refPort = refPort + 1) begin

          // Generate the charge balance equations at all ports
          for (thisPort = 1; thisPort < `QNRMESH2D_NPORTS; thisPort = thisPort + 1) begin

              // Extract the quasi-Fermi potential and evaluate its exponential
              Imref_min[thisPort] = sq_min*V(minport[thisPort],majport[thisPort]);
              LimExpImref = limexp(Imref_min[thisPort]/$vt);
             ...

              // Loop over all ports to compute the current in the selected port (thisPort)
             for (otherPort = 1; otherPort < `QNRMESH2D_NPORTS; otherPort = otherPort + 1) begin

                  // Assign the drift majority current
                 I(majport[thisPort],majport[refPort]) <+ Gdrift_maj[`index2D(`QNRMESH2D_NPORTS,thisPort,otherPort)]
                                                                           *V(majport[otherPort],majport[refPort]);
             ...
             end
       end
end
