1.x System Generator for DSP - FIR model gives error: "No class com.xilinx.ip. da_fir_v4_0.C_DA_FIR_UTILITIES_V4_0 can be located on Java class path"
描述
Keywords: System Generator, FIR, Java, error, no class com.xilinx
Urgency: Standard
General Description: I am using Matlab R12 with System Generator v1.0.1 or v1.1. When I run a design that includes the FIR block in System Generator, I encounter the following error in the Matlab console:
??? Error using ==> java_method No class com.xilinx.ip.da_fir_v4_0.C_DA_FIR_UTILITIES_V4_0 can be located on Java class path.
Other error messages reporting a FIR block failure may occur in the Simulink error window.
解决方案
The problem is that System Generator v1.x relies on DA_FIR_V4, which is delivered in (CORE Generator) IP Update #2 or later. In order to use the DA_FIR_V4 in System Generator, you must install IP Update #2 or later.
