I get some thoughts about it.
I use win 7 x64 and may be for using C code questa needs c compiler, but in linux it is standard gcc, but in my windows it can't find it and can't do what i want. Is it true?

Yes, it is true!
I forgot install gcc compiler to my system, but do...
Hello!
I tryed to run DPI with Questasim. I saw topics about it but version of sim changed and some things could be changed too.
My C code:
#include <svdpi.h>
//#include <gmodel_tb_top.h>
int factorial(int i)
{
if(i <= 1)
{
return 1;
}
else
{
return...
I use AD5542A - it has maximum SPI speed 50MHz
But in my design practice i get metastability on design with adc connected to fpga through isolator. And speed of that interface was 20 MHz, delay between clk on fpga net and miso net was about 26ns at worst case.
I need to do my design more...
Hello!
I want to write constraint for spi interface. FPGA is spartan-6 and i use ISE 14.7
Spi interface is the same as on picture. Clk line of SPI is the output of register.
I want to write constraints for this interface.
I tryed to write something:
NET "Data 1" OFFSET = OUT 8 ns AFTER...
Hello!
First question is about using Xilinx EDK. I use it for implementing axi system with my cores. I don't understand next thing: if i design my core with axi interface and implement it to the axi system, than if i change this core - i think there are two ways - with or without changing...
Hello!
I have a board with fpga spartan 6 and serializer sn65lv1023a deserializer sn65lv1224b. There is a channel between serializer and deserializer which can be work on speed from 120 to 720 MHz. In my case it works on 120 MHz.
My problem is that there many errors in receiving packets, when...
Hi all!
I tryed to calculate a value of sine and cosine functions using cordic algorithm. But it does not work in fixed point system and i wrote it as simple program.
Here is a code:
module cordic_test0(
);
real cordic_iter[15:0];
real angle;
integer i = 0;
real xi;
real yi;
real zi...
Hello!
I use in project FPGA and NAND Flash MT29F04G01
I developed spi core for this chip and try to read/write data from/to this Flash.
There is a cache register, in which data writing first, and then transmiting in NAND memory array.
In reading data transmiting from NAND memory array to cache...
