Vivado 2016.2 Simulator doesn't support System Verilog $cast or $sformatf

Question

Using the Vivado 2016.2 simulator I need to cast an int to a string in System Verilog but $cast and $sformatf are not supported. What other functions or methods are available to me in order to successfully typecast an int to a string?

Answer 1

There are the following other ways

string s;
int i;

s.itoa(i); // converts int to decimal string
$swrite(s,"%d",i);
$sformat(s,"%d",i);

If none of those work for you, then you'll need to write a binary to decimal conversion routine yourself.
