wire                       jerry_BREADY;

It did not work for me.
I am getting blanks where the evaluated number should be.
Are you running a certain version of awk?

Thank you.

This does not work for me.
I am getting blanks where the evaluated number should be:

Code:
wire        [:0]       jerry_AWADDR;
wire                       jerry_AWVALID;
wire         [:0]       jerry_AWCACHE;

wire         [:0]       jerry_AWSIZE;
wire         [:0]       jerry_AWBURST;
wire        [:0]       jerry_WDATA;
wire         [:0]       jerry_WID;
wire                       jerry_WLAST;
wire         [:0]       jerry_WSTRB;
wire                       jerry_WVALID;
wire                       jerry_BREADY;

Which version of awk are you using?

Thank you.
