I want to make an ISA interface between one Xilinx Virtex-II FPGA and a PC/104
single board computer. ISA bus is delivered through PC104 bus and is 5v, so I use
level converters to mach FPGA 3.3v to this. The problem is when I place FPGA on ISA bus, the computer can not be started! (The...
ERROR with Configuration
I want to use a Virtex-II plug-in board module. The following error message occurs when I initialize the JTAG chain:
"ERROR:IMPACT:477 - The BSDL for device 'unknown' is out of date. Please check your installation."
After I select OK, It shows 9 "unknown"...
I'm looking for a free good controller core for micron ddr sdram "mt46v16m16" to be implemented on xilinx virtex2 or spartan3 FPGA.
I would be pleased if you help me to find that.
If this core supports burst lenght = 8 and bidirectional DQS signal, it's much better for me.
I have designed an ATA UDMA controller on Xilinx Spartan-3 device.
When I use 40-conductor cable, it works well (UDMA-2 is OK) but when I use 80-conductor cable, it does not work!(even UDMA-0)
I think there is a problem with my IDE interface(physically).
What do you think?
Could you tell me about manufacturers that ecomplish full process of making a PCB:
designing, fabrication, components purchase, mounting and assembly?
I need to 5 samples of my system and should deliver them very soon!
