为串联参数分配localparam？

Question

Here's what I'm trying to do . . .

localparam nine1 = {3{4'b0000}, 4'b1001};
localparam nine2 = {2{4'b0000}, 2{nine1}};

Is it possible to assign a localparam with a concat satement and then use that localparam in another localparam assignment? It seems like it would work, but I might have fuddled something up. This is not system verilog by the way.

Answer 1

Well, the error was that I wasn't wrapping my replication statements in {} inside the concatenation .

localparam nine1 = {{3{4'b0000}}, 4'b1001};
localparam nine2 = {{2{4'b0000}}, {2{nine1}}};

Subtle, but important.
