parameter array declaration error
Apr 17^th, 2007, 5:04am

Hello

In my code I try to use the similar instruction as in example in chapter 3.2.3 "Parameter arrays" of Verilog-AMS
Language Reference Manual:

Code:

parameter real fpoles [0:4] = {5.727, 1.24E+07, 1.84E+07, 2.38E+07, -3.57E+07};

The parser gives the following error message:

In Affirma-AMS, parameter array declaration is not supported.

Where am I wrong?

Regards

Pavel

Parameter arrays are an extension supported in Verilog-AMS. I'm just saying, a number of AMS simulators are really Verilog-1364 simulators with some amount of the AMS extensions supported, and it looks like yours doesn't have everything you want.

The simulator message does seem to indicate that the vendor knows it's a valid construct, but unsupported.
