Subject: [oc] task/module in case statement
Is it possible to call up a module or task from within a case statement?
I'm using the following code and when I place the sub-module in the
case statement I get an error?
module controller_top(iclk, led);
input iclk;
output led;
reg clock_count;
always @(posedge iclk)
begin
case (clock_count)
0: begin
clock_count = clock_count + 1;
wb_write u1(iclk,led);
end
endcase
end
task wb_write;
input clk;
output q;
reg [19:0] COUNT;
initial
begin
COUNT=0;
end
assign q=COUNT[19];
always @(posedge clk)
begin
COUNT = COUNT + 1;
end
endtask
endmodule
