1.0.1 System Generator for DSP - FIR model does not function, gives error: "No static Java method 'getResultWidth' found for Java class 'com.xilinx.ip..."

描述

Keywords: System Generator, FIR, Java, error

Urgency: Standard

General Description:
I am using Matlab R11 with System Generator v1.0.1. When I run a design that includes the
FIR block in System Generator v1.0.1, I encounter the following error in the Matlab console:

??? Error using ==> java_method
No static Java method 'getResultWidth' found for Java class
'com.xilinx.ip.da_fir_v4_0.C_DA_FIR_UTILITIES_V4_0'.

Other error messages reporting an FIR block failure may appear in the Simulink error window.

解决方案

The problem is that System Generator v1.0.1 relies on DA_FIR_V4, which is delivered in
(CORE Generator) IP Update #2. In order to use the DA_FIR_V4 in System Generator,
you must install this update.

Download IP Update #2 from:

http://support.xilinx.com/ipcenter/coregen/updates.htm

For instructions on how to install the update, please see the 3.2i IP Update #2a "Installation
Instructions & Release Notes" at the above URL.

After this is done, re-open Matlab/Simulink and run your System Generator model; the problem
will be fixed.
