    A little numbers question (verilog).

    I'm working on a verilog project(Not C I know, But I think this transfers over. Haven't found a good verilog board yet)

    So i'm working through some demo code/ best practices to try to do a little learning and I havnt seen this before:

    Code:
    assign HEX7 = 7'h7f; 
    assign GPIO_1 = 36'hzzzzzzzzz;
    A <= 4'b0000;
    A <= A + 1'b1;
    specifically the numbers. I think 1'b1 is binary 1. is the number before the ' the base and the number after the number? still seems odd to do things in base 36 and 4.

    any help is greatly appreciated! thanks!

    I'm thinking you'd be a lot further ahead asking your questions on a Verilog forum....

    Any recommendations for a good one? I figured this was a basic numerical notation, I think I've seen it on C and assembly before so figured it might transfer over.

    Ok... I think I got it. I think the number before the ' is the number of bits, and then b for binary, h for hex and then the value... the one that threw me off was the

    Code:
    assign GPIO_1 = 36'hzzzzzzzzz;
    i thought hex only went up to F, so this one is still confusing me.
