Issue with `uvm_register_cb macro with parameterized classes


Recommended Posts

Hi,

When I try to use the `uvm_register_cb macro with a parameterized class, I run into the below compile problem.

Error-[sE] Syntax error

Following verilog source has syntax error :

"scoreboard_c.svh", 178 (expanding macro): token is '#'

`uvm_register_cb(scoreboard_c #(T_EXP,T_ACT), scoreboard_cb_c #(T_EXP,T_ACT))

The uvm_register_cb macro expands to the below code:

/*=== scoreboard_c.svh(178), macro uvm_register_cb */

static local bit m_register_cb_scoreboard_cb_c #(T_EXP,T_ACT) = uvm_callbacks#(scoreboard_c #(T_EXP,T_ACT),scoreboard_cb_c #(T_EXP,T_ACT))::register_pair("scoreboard_c #(T_EXP,T_ACT)","scoreboard_cb_c #(T_EXP,T_ACT)");

If I replace the macro with below updated code (remove #(T_EXP,T_ACT) from the member name), everything works.

static local bit m_register_cb_scoreboard_cb_c = uvm_callbacks#(scoreboard_c#(T_EXP,T_ACT),scoreboard_cb_c#(T_EXP,T_ACT))::register_pair("scoreboard_c#(T_EXP,T_ACT)","scoreboard_cb_c#(T_EXP,T_ACT)");

Is this a known problem in uvm1.0?

Regards,

Pinh

It does appear to be a limitation (it uses the class as part of the generated variable name). I didn't see any reference to it in the Mantis system.

One workaround would be to typedef your parameterized class and use that for the macro.
