Problem with multple clcok domains
Hi I am writing synthesizable Verilog code for a DPRAM. It has two ports, Port A and Port B. For each port theres is a separate clock and separate clock_enable. This is the code I wrote reg [ 4: 0] read_addr_a; reg [ 4: 0] read_addr_b; always @ (posedge clock0) if (clocken0) begin ... 20 Feb 2006 14:41

Addressing BRAM in a V2 pro
Hi all, I'm designing a IP core for a Virtex 2 pro board. This IP need to store data in BRAM. I have been searching how I can adress the BRAM with my IP but I haven't found it. Can anyone tell me how you can do this? Thanks Mich ... 23 Feb 2006 10:09

PC104+ Card
There have been a number of posts over the last few months about availability, or not, of PC104+ FPGA boards. In a couple of weeks time and with a little bit of luck we should be showing Hollybush1 at DATE for those that are interested in this board type. The board has a nice easy expansion capability and if a... 18 Feb 2006 11:11

Xilinx System Generator Black Box
A few weeks back I posted about importing a VHDL, actually a Xilinx Core, into a system generator project as a black box. The help files give explicit instructions under a heading specifically titled "Importing a Xilinx Core into a Simulink Model". Well the issue was about inserting a CE pin into a core wrapper... 18 Feb 2006 09:38

Communication between FPGA and PC with ethernet
Hello I have to make an connection to a FPGA-borad. http://www.celoxica.com/products/rc300/default.asp This board only supports ethernet communication with the mac-layer. Now I have to build an app that can send data(in my case images) to the board. My question is now how can i send data using the mac-lay... 19 Feb 2006 18:21

ModelSim Licence problem
I am using xilinx Tool Ver 6.3. And Modelsim 5.8. Due to some reasons I uninstalled modelsim. After I installed it again I faced a problem related to license . ModelSim is installed. and While running it asks for license. At licensing Wizard of ModelSim, I choose a license file which was there previously( we k... 14 Feb 2006 11:17

Problem programming Altera flex 10k100 & EPC2
I have a working prototype board from yesteryear with a Flex 10K100GC503-3 FPGA and an EPC2L120 configuration device on it. I realize these are geriatric parts by todays standards, but if I can get this board working, it will do what I need. Altera is no help - pointing out that the part was EOL'ed in 1993. This... 14 Feb 2006 11:17

EDK Simulation
I am simulating an EDK MicroBlaze embedded system using NC-Sim. Whenever I open a waveform window and try to simulate I get errors. Here they are: ncsim: *E,SST2ER: SST2 interface error: Permission denied. ncsim: *E,NOSHMO: cannot open SHM database file 'waves.shm'. So it seems I cannot create or modify a dat... 13 Feb 2006 21:43

Altera EPLD
In a project I use the Altera EPM3256ATC144-10. Now I have the necessity to make some changes to the project, but I don't have enough macrocells in the actual devices. Alteras doesn't have a pin-to-pin compatible EPLD with the EPM3256ATC144-10 but with more macrocelles (about +40%). What of you knows a devices ... 14 Feb 2006 16:31
