    Reduce synthesis and implementation time in the VIVADO

    I was not familiar with the Incremental implementation before. Using it, the implementation time was reduced by half. It was a great experience for me. Based on my searches and studies It is recommended for when the design changes are below 5% Thanks a lot. 1626684064 Thanks a lot...

    Reduce synthesis and implementation time in the VIVADO

    Hi guys I have an RTL design project in the VIVADO 2020 developing environment, and my implementation platform is ARTIX 7. In my project, I have about 30 trusted and tested VHDL files and cores without the need to change. I always change one of the VHDL files and do not change the other files...

    How to concatenate 8Bit binary EEPROM files to get a 32Bit binary file.

    I have 4 binary files read backed from EEPROMs. I used "XELTEK SUPERPRO 3000U" programmer to read back EEPROMs, but I did not find any option or tools to merge horizontally these files.

    How to concatenate 8Bit binary EEPROM files to get a 32Bit binary file.

    Hi I am working on a reverse engineering project based on the MC68020 Motorola 32Bit processor. The program is stored in 4x8Bit EEPROM as the instruction memory. However, my EEPROMs only have 8bits data output, but I want my instructions to be 32bits long. How can I combine these four binary...

    DDR3 Memories on SOC of Xilinx FPGAs

    Hi I have recently started to design a custom schematic based on Zynq7000 FPGAs. For better attitude toward Zynq7000 hardware design , I have searched in many sample boards produced by Xilinx Co. In many of them two types of DDR3 memory are available , one for PS and another one for PL.In most...

    Problem with exporting Gerber files in the Altium

    Hi I am trying to export my gerber files from an Altium PCB project .My board dimensions is 960mm x 45 mm (it’s a long board with strange dimension). In File>Fabrication output>Gerber Files> Advanced Tab I have changed Film size options (X,Y) with large enough numbers (Like 1000mm or 2000mm).But...

    A strange error in SDK ([microblaze_0/lib/libxil.a] Error2)

    Hi everybody I tried to implement a very simple Microblaze hardware on my custom board based on XC3S400 FPGA. But in the first step of developing code in the SDK environment I have faced with a strange error; after exporting my platform into the SDK environment and before any build command or...

    Connecting high depth SPI Flash Memory to SSP Buses in LPC1788

    Hi I am trying to connect a 16MB SPI Flash Memory (SST25VF016B) to one of SSP buses in LPC1788 but after some studies in LPC1788 datasheet I realize that the Address length in SSP bus can vary only between 4 to 16 Bits. Obviously I need 24 Bit address length in my application. In your point of...

    Problem with RS232 to GPIB Converter

    Yes,even i captured my serial port with "HHD Free Serial Port Monitor" software, and i saw my request string was correct. Serial port monitor showed my request string was: 2A 49 44 4E 3F 0A that's equal with: *IDN?<LF>
