Hi,

I want to run perl command with dynamic argument in SystemVerilog. And I use Cadence IUS583.

When I try to pass a string to $system(), the ncvlog said "Using String without index is not supported in the given context."

The code I write like below,
//---------------------
string perl_cmd_str = "";

$sformat(perl_cmd_str,"perl ./perl/test_opt_file.pl -a %0d -b 4", data_a);
$display("string is %s\n", perl_cmd_str);

$system (perl_cmd_str);
//---------------------

Any suggestion on how to input string to $system()?

Thanks!
Davy
 

Hi,
Checkout this!
Which simulator ur using??? I have ncverilog 5.6 which does not support
string construct yet!

Code: 
reg[100*8:1] perl_cmd_str = "";

$sformat(perl_cmd_str,"perl ./perl/test_opt_file.pl -a %0d -b 4", data_a);
$display("string is %s\n", perl_cmd_str);

$system (perl_cmd_str);

Hi nand_gates,

Thanks a lot! I will try your suggestion and tell you the result.

BTW, I use Cadence IUS583 (i.e. ncverilog 5.83 which support SystemVerilog).

Best regards,
Davy
