Xilinx chip FPGA clearance

Clearing the FPGA chip is to return the FPGA chip to the blank state before re -programming.This article will introduce how to use the Xilinx chip to remove the FPGA in detail.The following are the steps to remove FPGA:

Step 1: Close the FPGA power supply

You should turn off the power of FPGA before clearing FPGA.At the same time, you should ensure that there are no unused cables and components around FPGA.This can avoid any unnecessary damage and power stability.

Step 2: Configure the Mode Select to “000”

FPGA chip usually has a Mode Select pin to choose different operating modes.During the FPGA removal, you need to configure the Mode Select to “000”.You can refer to the Xilinx chip document to get detailed information.

Step 3: Configure the M2/M1/M0 pin to “000”

Configure the M2/M1/M0 pin to “000” is the key step to remove FPGA.These pins are usually used to choose different operation modes and configuration methods.Make sure that the pin is configured correctly, otherwise your FPGA will not be cleared normally.

Step 4: Ground the PROGRAM pin of FPGA

When you remove FPGA, you need to ground the Program pin.This is an important step to switch the FPGA chip to the programming mode.Make sure this pin is correctly connected, otherwise the programming process may fail.

Step 5: Configure FPGA’s Done pin to high level

After removing FPGA, the Done pin will output high level signals.This shows that FPGA has been cleared.You can connect the Done pin to an appropriate LED or oscilloscope to ensure that the FPGA has been successfully cleared.

Step 6: Open the FPGA power supply

After completing all the above steps, you can turn on FPGA’s power and wait for FPGA to complete the clearing.In this process, do not break the power supply or re -connect any pins.

Step 7: Verify that FPGA has been cleared

Once the FPGA is successfully cleared, you can verify the chip.You can use the software and tools provided by the Xilinx chip to verify whether the FPGA has been cleared correctly.In this process, you need to ensure that FPGA no longer includes previous configuration files and data.

Step 8: Re -program FPGA

Once the FPGA is successfully cleared, and you have verified it from it, you can start to re -program FPGA.In this process, you can choose to use the software and tools of the Xilinx chip, or use other compatible software and tools.

in conclusion

Clearing FPGA is an important step to return the FPGA chip to the blank state before re -programming.This article introduces how to use the Xilinx chip to remove FPGA.Please follow the above steps one by one, and use the appropriate tools and software to verify the FPGA to ensure that the FPGA has been successfully cleared.
