Title: 2D vector (i.e. array) as an input for an analog function?
Post by Vince Lee on Feb 24^th, 2014, 3:21pm

Hi, I wonder if it is possible to pass a 2D vector into an analog function as an input argument? e.g.

analog function myfunc;
input x[0:2][0:2];
real x[0:2][0:2];
...
endfunction

Thanks!

There's an example in LRM 2.3.1, section 4.7.1:

Example 3 — Initialization of a vector variable
The analog user defined function called arrayadd adds the contents of a second array to the first.

Code:

analog function real arrayadd;
inout [0:1]a;
input [0:1]b;
real a[0:1], b[0:1];
integer i;
begin
for(i = 0; i < 2; i = i + 1) begin
a[i] = a[i] + b[i];
end
end
endfunction

I can't say whether it works in all simulators.
