Please share,  Anybody have DDR4 Verification interview questions

How memory chip controller interact with Dram(DDR) controller in ASIC??

What is the problems?
Do you want to get a plan of this development?

Yes sir I want advice how can created if there is any example that will allow Good.
Thank you sir, 🙏

Sir,which FPGA is suitable for basic image processing

I've succeded with the lowest Cyclone V chip. I think Cyclone III/IV also will be suitable. It depends on your image source.

you need to understand at least three basic things:
1) video interfaces and i/o you might need: camera links, display port, sdi or whatever
2) what type of processing you want to perform? Go and check logic utilization/requirements for video processing IPs from Intel or Xilinx
3) What's the data stream to process? HD and 8K video will require different FPGAs

Just 5 characters...intel

My project is just implementation of median filter technique on any image

Impulses noise image

Try to find chip with enough block memory for one frame))

Is Spartan 3 is ok

Any one know how to do a pwm in verilog in Spartan 6?

Using counters? Which frequency and quantization you need?

Welcome to the Internet, let me be your guide here

Ок.
1. Create small testbench with name stand. It must  generate clock, such on ZedBoard, parameters for impuls and receive impuls.
2. Create component, with name for example: impulse_gen.
It must have several ports:
- clk — clock
- reset
- imp_period - bus for setting period
- imp_width - bus fir setting impulse width
- impuls_o - it is your impulse
3. Insert impulse_gen into stend.
You must run the simulation session and you must view no impulses.
Which simulator do you prefer ?

I notice - simulation is very important. You must start development with create design for simulation.

4. Create a counter for period into impulse_gen
5. Create another counter for width

By this step you will create simple component for generating the impulse.
On the next step - setting parameter from zynq.

By comparing a triangular wave with a square wave.
So.that the duty cycle can be variable

Is it pwm or audio dac?
