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.
