This is my project with 3 files: test bench(tb_test_struct.sv), dut(test_struct.sv) and include(tst_struct_inc.svh)
tb_test_struct.sv
`timescale 1ns/1ns
`include "tst_struct_inc.svh"
module tb_test_struct;
tst_t abc;
test_struct t0();
initial begin
#100;
$display("tb");
abc.a = 33;
t0.printi(abc.a);
t0.prints(abc);
end
endmodule: tb_test_struct
test_struct.sv
`timescale 1ns/1ns
`include "../tb/tst_struct_inc.svh"
module test_struct();
task printi(int ivar);
$display("ivar=%0d", ivar);
endtask: printi
task prints(tst_t svar);
$display("svar.a=%0d", svar.a);
endtask: prints
initial begin
$display("Run test_struct");
end
endmodule
tst_struct_inc.svh
`ifndef TEST_STRUCT_INC_SVH
`define TEST_STRUCT_INC_SVH
typedef struct {
int a, b, c;
} tst_t;
`endif
Compilation with questa is ok but with 1 error in simulation:
“# ** Error: tb_test_struct.sv(17): (vopt-13216) Arg. ‘svar’ of ‘prints’: Illegal assignment to type ‘test_struct_sv_unit::struct tst_t’ from type ‘tb_test_struct_sv_unit::struct tst_t’: LHS and RHS types do not match.”
From what I understand, for the compiler, the structs tst_t in tb_test_struct.sv and test_struct.sv are different (different “unit”).
How is the right way to call a task (in different module) passing a struct as argument?.
