Sigasi Studio warns about unused macros. Unused macros are often a side effect of code modifications. They can be safely removed.
`define UNUSED_MACRO(a) $display(a) module sumff(input clk, rst_n, logic[31:0] d1, d2, output logic[31:0] q); wire logic[31:0] sum; assign sum = d1 + d2; always @(posedge clk or negedge rst_n) if (~rst_n) q <= 32'b0; else q <= sum; endmodule
This rule can be disabled for your project, or its severity and parameters can be modified in the project linting settings. Alternatively, it can be manually configured with the following template:
