问题 I have installed fftw C library succefully on my linux system. Here is more info about fftw c => http://www.fftw.org/ I have a sample C code which can call fftw C functions successfully. Below is a C ccode and command to run the C code: Code: #include <stdio.h> #include <stdlib.h> #include <stdint.h> #include <math.h> #include <fftw3.h> int main(void) { double FFT_in[] = {0.1, 0.6, 0.1, 0.4, 0.5, 0, 0.8, 0.7, 0.8, 0.6, 0.1,0}; double *IFFT_out; int i,size = 12; fftw_complex *middle; fftw_plan

问题 Problem Description : I design in SystemVerilog and write the testbenches in the same language. I want to be able to compile my design and test different functions during simulation in the way you would using an interpreter with e. Ideally, I would have a terminal pop-up upon simulation when the simulator hit some line. Potential Ideas : I've looked at the DPI-C and it seems like I would have to "export" all tasks in my project in order to run them from the interpreter. However, I'm not sure

问题 Hi I am getting below error while compiling a c code using gcc /usr/lib/gcc/x86_64-redhat-linux/4.4.6/../../../../lib64/crt1.o: In function `_start': (.text+0x20): undefined reference to `main' collect2: ld returned 1 exit status I am trying to import the fftw() function into SystemVerilog. Here is my code #include <stdio.h> #include <stdlib.h> #include <stdint.h> #include <math.h> #include <fftw3.h> void fftw(double FFT_in[],int size) { double *IFFT_out; int i; fftw_complex *middle; fftw
