I must be doing something really stupid here.
The problem I have is that I seem to have a disagreement between instruction register values in TCL script and in Verilog.
In TCL:
In Verilog:
What I'm observing is a sequence of RESETHI-(3 seconds)-RESETLO on my device when it SHOULD be RESETLO-(3 seconds)-RESETHI
Any ideas please?
The problem I have is that I seem to have a disagreement between instruction register values in TCL script and in Verilog.
In TCL:
Code:
set RESET_HI_CMD 11
set RESET_LO_CMD 12
..
device_virtual_ir_shift -instance_index 0 -ir_value $RESET_LO_CMD
setJTAGBypass
after 3000
device_virtual_ir_shift -instance_index 0 -ir_value $RESET_HI_CMD
setJTAGBypassIn Verilog:
Code:
localparam RESETHI = 4'b1011; // Definitely 11, same as TCL
localparam RESETLO = 4'b1100; // Definitely 12, same as TCL..
..
if( opco[3:0] == RESETLO )
begin
notReset <= 0;
oLED1 <= 0;
oLED8 <= ~ oLED8;
end
else
if( opco[3:0] == RESETHI )
begin
notReset <= 1;
oLED1 <= 1;
oLED7 <= ~ oLED7;
endAny ideas please?
