Synplify synthesis error
>Does it simulate OK? Sometimes the files need to be added in correct order, i.e. the file with the package must be added before any library units that make use of it. IIRC you can drag them around in the gui to alter the order, or check the .prj file which should have lines such as: add_file -lib work m... 23 Apr 2010 17:24

Efficient Multi-Ported Memories for FPGAs
Hi All, I've recently published a paper exploring how to implement memories with multiple read and write ports on existing FPGAs. I figured it might be of interest to some. Summary, paper, slides, and example code are here: There are no patents or o... 27 Apr 2010 21:18
clock routing to generic IO pins?
Hi, does anyone know if there is such a thing as clock IO for Xilinx FPGA?? If i were to design my own PCB board with an FPGA on it, do i necessarily have to route the clock from the on-board oscillator directly only to the clock IO pins? din consider this before, but thought i get some opinions to be sure ... 20 Apr 2010 15:42
Need to run old 8051 firmware
Hello all I need to run an old firmware for a Siemens SAB 80C537 microcontroller unit (MCU). The MCU is now obsolete (it's from the late 1980s). The firmware is compiled from several thousand rows of assembly language. It would take a long time to understand the code and re-program it in C. So ... 24 Apr 2010 12:46
