How can i store all the LUT and leaf cells used to implement a design in to a text file ?

[SSandeep19]

I have a design check point file post implementation in Vivado holding the LUT information. I want to save theat information in to text file. The text file should have information like the name of the LUT the slice of the FPGA etc. Is it possible to do using rapid write ?.

Thank you.

Sure, here is some example code that loads in one of our test DCPs and write outs a text file:

package com.xilinx.rapidwright.examples;

import java.io.BufferedWriter;
import java.io.FileWriter;
import java.io.IOException;

import com.xilinx.rapidwright.design.Cell;
import com.xilinx.rapidwright.design.Design;

public class WriteLUTInfoToFile {
    public static void main(String[] args) throws IOException {
        Design d = Design.readCheckpoint("test/RapidWrightDCP/bnn.dcp");
        try(BufferedWriter bw = new BufferedWriter(new FileWriter("lutInfo.txt"))){
            for(Cell c : d.getCells()) {
                if(!c.getBEL().isLUT()) continue;
                bw.write(c.getName() + " " + c.getSiteName() + "/" + c.getBELName() + " " + c.getType() + "\n");
            }            
        }
    }
}

Thank you for the reply. I am new to this environment and little confused i hope you can help me out here. I did automatic install setup and got the IDE as shown in below screen shot.

My goal is to take a post implementation design check point file from Vivado and get all the slices used by the design into a text file. The FPGA i am using is kc705 (xc7k325ffg900).

What should i do after installation ? I see there are couple of IDEs do i need them but i already have Vivado. Is there any example you can provide which is similar to my task.

Any help is much appreciated. Thank you

Thank you for your patience and response.
I am able to execute the program but where can i find the LUT information below is how the terminal looks like.

Found it thanks.

[SSandeep19]

To get all the flip flops information can i just change
if(!c.getBEL().isLUT()) continue; to if(!c.getBEL().isFDCE()) continue;

Will that work ?

[clavin-xlnx]

BEL.isFDCE() is not a method that I am aware of. However, there is BEL.isFF().

Got it thanks!! Is there any way to write all the elements used by the design ? (LUT,FF,BRAM,DSP etc)
