I've tried creating a 'real' type value array in the following way in Icarus Verilog:
parameter width = 10;
shortreal b [width-1:0] = {0.0181,0.0487,0.1227,0.1967,0.2273,0.1967,0.1227,0.0487,0.0181};
Gives the following error:
error: Cannot assign to array b. Did you forget a word index?
I went through the icarus verilog src code error messages and the explanation to this one is "Special case: The l-value is an entire memory, or array
slice". This is, in fact, an error in l-values. Detect the
situation by noting if the index count is less than the
array dimensions (unpacked)", which I assume means that the array index size differs from the declared one [width-1:0], which isn't true if I understand.
I've also tried:
parameter width = 10;
parameter [32:0] b [width-1:0] = {0.0181,0.0487,0.1227,0.1967,0.2273,0.1967,0.1227,0.0487,0.0181};
but without any success.
Using Icarus Verilog with -g2012 flag (for SV support)
It is only legal to use so-called array concatenation if you fill the entire array. You array have 10 elements, but there are only 9 on the right hand side:
parameter width = 10;
shortreal b [width-1:0] = {0.0181,0.0487,0.1227,0.1967,0.2273,0.1967,0.1227,0.0487,0.0181,0.0181};
