LogiCORE FIR Compiler v3.0 - Why do I see errors when I open the GUI and try to customize the FIR Compiler for a Spartan-3/3E/3A/3AN device?

Description

Why do I see errors when I open the GUI and try to customize the FIR Compiler for a Spartan-3/3E/3A/3AN device?

This issue does not affect the Spartan-3A DSP devices.

When opening the core in ISE Project Navigator, you will see the following error message:

"The program [_ipguilauncher.exe -cg_exc_inp C:\Designs\Scratch\dummy_s3a_700\tmp\_cg\xil_3852_42.in -cg_exc_out C:\Designs\Scratch\dummy_s3a_700\tmp\_cg\xil_3852_42.out ] caused a problem and is going to close."

And then:

"9.1.03i - Xilinx CORE Generator IP GUI Launcher i+IP+121052(c) 1995-2007 Xilinx, Inc. All rights reserved. ERROR:coreutil - sim - First_Column_Length: Invalid Integer range '[1..0]'.An Error occurred during Customization."

When opening in CORE Generator, you will see the following error messages:

ERROR:sim - First_Column_Length: Invalid Integer range '[1..0]'.

ERROR:sim:228 - An invalid core configuration has been detected during Customization. Core parameters

will be reset to their default values.

ERROR:sim:178 - Attempting to set invalid value: (First_Column_Length, 16).

ERROR:sim - First_Column_Length: Invalid Integer range '[1..0]'.

Solution

This is a known bug in the FIR Compiler v3.0 that will be fixed in the FIR Compiler v3.1, currently scheduled to be released in ISE 9.2i IP Update 1.

It is only a superficial error; the core will generate without any problems.

You can also work around this problem by using the FIR Compiler v2.0, or the older MAC FIR v5.1 and DA FIR v9.0, when targeting a Spartan-3/3E/3A/3AN device.
