Xilinx DCM Block Stability Issues
Hi, We're using one of the global DCM blocks in a Xilinx Spartan 3E to regenerate/deskew an important clock in our application. The clock has an input frequency of 31.5 MHz and we're using the 270 phase of the X1 output of the block. However, we've observed that the block seems to be marginally stable. At ra... 22 Jun 2010 21:32

Difficulty with Xilinx FPGA configuration using Platform FlashPROM

Xilinx Timing Constraings
I'm no luck figuring out how to implement the timing constraints for something that, to my mind, ought to be pretty simple. I'm connected to an external synchronous logic chip. For now let's call it a regular 74HC74 flip flop, but the details are unimportant. My FPGA outputs D and CLK to the 74HC74, and read... 23 Jun 2010 15:03

Asynchronous FIFO in Spartan6
Hi, I am trying to use this FIFO design in a Spartan6: http://www.asic-world.com/examples/verilog/asyn_fifo.html Doing so makes Xst emit a shrill warning (Xst:3002) because a latch construct does not play well with the Spartan6 architecture, as it has both an asynchronous set and reset. And as the warning says... 22 Jun 2010 14:54

Programming the Actel Smartfusion Eval Kit in Linux
Hi, I recently got the Actel Smartfusion eval kit. Since I use Linux, I am running the windows Libero IDE under wine. While the application runs fine under wine, I am not able to program the device with the Flashpro software. Seems like it is not able to talk to the programmer. I know this is as much a wine is... 23 Jun 2010 07:18

Why is Google so F****** dense about SPAM?
Why is Google too dense to fix their SPAM problem? There are so many ways they could address the problem and as far as I can tell, they treat it as a PR concern and have tried to give us a control that does nothing! You can flag posts as being spam very easily now. Each post has a link at the bottom that lets yo... 25 Jun 2010 14:15
