Mixture of case and if-else statements

[Saad Bin Shafique]

Hi. I have used combination of case and i-else statements. Now the problem is that first case executes successfully but second case never executes. While synthesizing on xilinx, it gives me an error saying that "case condition never applies". Does anybody know what is the problem?

Thanks

@Saad Bin Shafique,

I use "if" statements within case statements all the time without a problem, so I don't think that's what's going on in your code.

But your case numbers, 001, 010, etc .... I think you intended these to be binary, but I don't see any 3'b in front of them, such as 3'b000, 3'b001, 3'b010.  If the synthesizer took these to be decimals, and you only fed your case statement with a three bit value, that would probably explain what you have going on.

I've got two questions.

Why is this post in the project vault?

Why is using the Vivado or ISE simulator so burdensome that simple syntax problems require posting such a question?

Really... I don't understand this.

@zygot,

Yeah, that's okay, he didn't understand what was going on either.
