connect uvm_analysis_export (SV) and tlm_aanalysis_port (SC) with UVMC

[samng]

Hi,

 

I am trying to connect uvm_analysis_export (SV) and tlm_aanalysis_port (SC) using UVMC like the following:

 

    uvm_analysis_export #(obs_xact#(WL,DEP)) sc_export;
 

    uvmc_tlm#(obs_xact#(WL,DEP))::connect(sc_export,"fft_ap");

 

but I got the follow error message:

 

  Incompatible complex type usage in task or function call.
  The following expression is incompatible with the formal parameter of the
  function. The type of the actual is 'class
  uvm_pkg::uvm_analysis_export#(class test_pkg::obs_xact#(12,512))', while the
  type of the formal is 'class uvm_pkg::uvm_port_base#(class
  uvm_pkg::uvm_tlm_if#(class test_pkg::obs_xact#(12,512),enum
  uvm_pkg::uvm_tlm_phase_e))'. Expression: this.sc_export
  Source info:
  uvmc_tlm#(test_pkg::obs_xact#(12,512),uvm_pkg::uvm_tlm_phase_e,uvmc_pkg::uvmc_default_converter#(uvm_pkg::uvm_object))::connect(this.sc_export,
  "fft_ap", null ...
 

Isn't uvm_analysis_export is extended from uvm_port_base#(uvm_tlm_if#())?

 

Thanks

Hi Sam,

   in the error message it mentions uvm_tlm_phase_e, which is a TLM2 feature. Are you sure you've declared both sides using uvmc_tlm (not uvmc_tlm2)?

 

kind regards

Alan, thanks for the reply.

 

I think uvmc_tlm is for TLM2 and uvmc_tlm1 is used for TLM1 connection. Is that right? I think tlm_analysis_port is a TLM2 feature, right? 

 

Thanks,

Sam

No analysis ports are TLM1 (in fact in SystemC they are technically a utility, i.e. not part of the standard).

I looked at the docs and it seemed to say you have to use uvmc_tlm (which I think is tlm1) for analysis ports,
