Memory inferencing speed has been improved hugely in release 2000.1b.

Hi, I started to have problems with my 40k gate Spartan FPGA design as I added more features. The FPGA is used mainly as a glue logic, performing address decoding, clock generation, frame resizing and frame synchronization. Initially when the design is relatively small (about 25% resources ultilised), the problems I faced was mainly due to my error. However, as I added the final protion that is frame synchronization (to frame shift 3 PCM streams) using shift register buffers, I find that these buffers would not work. The buffers have been functionally verified to be working. The rest of the design was still working fine. I have tried 2 implementations for the buffers shift register type and pointer-loaded type, but both failed. The output is not the same as the input. I wonder if it is due to the higher ultilization of the FPGA of 50% at this time? Would adding a timing constraint file help? I am not familiar with timing constraint and would like some advice before I take the plunge into adding this to the design. If I were to use a larger FPGA that lowers the ultization from 50% to 25%, would that help? I am using Xilinx Foundation 2.1i Neo Wei Thiam CET Technology Pte Ltd SingaporeArticle: 28905

PCBs with components attached are typically shipped in conductive bags. So the battery would be subject to discharge through the resistance intrinsic to the bag. This resistance is probably on the order of 100K to 1M ohms. I must admit, I have not actually measured the resistance of a typical anti-static bag.

Dear colleagues, What is your experience: what size of VIRTEX (SPARTAN-2) chip is needed to implement something like 8 multipliers 16*16 bits, 10 ns per multiply? 100 ns per multiply? Are there any multipliers in standard XILINX library for Virtex? If not, where they are? Thanks, Alex Sherstuk sherstuk@iname.comArticle: 28907
Debug your circuit the normal way: If the function simulates logically, use the timing analyzer to find critical paths. If everything simulates ok, but fails physically: Lower the clock frequency to see whether you have a real timing problem ( unlikely ). You can also heat the chip, and increase/decrease Vcc, but stay within the guaranteed limits.

What is your clock frequency? I am not sure about Spartan but I have worked on 4000xv series. It seems that 50% CLB usage is be ok if your clock is about 10-20MHz. I was trying to route a design which utilizes 70% CLB with a 50MHz clock on a xc40150xv. Although some of the signals are clocked at lower frequencies, I specified all the timing constraints in a ucf file. Still the PAR cannot satisfy all the signal paths. If you specify the timing constraints, you can see which signals paths are difficult to route, and then modify your logic to "help" the compiler.

Except where you're driving the address bus of a parralel bank of say 4 128K*8 Rams. If you had an instance where the address rolled over from 0 to 2^17 you'd be driving a load of 72 pins from 0 -> 1. This could potentially give you bad ground bounce problems. If you were driving the address bus with a grey code counter (and it's ram so you may as well) you'll always only be driving a load of 4 inputs on each address transition. It'll not help with power consumption, but might help but EMC/grounding issues. Nial.Article: 28914
Hi all, I run into a little problem trying to control the setup time of an input pin to an XC4044XLA device . Here it goes: I want to specify a NODELAY attribute to an input pin to minimize the setup time. I want to do it in the UCF file. I used the syntax : NET "DATA_IN<0>" NODELAY; and it was ignored by the software (Alliance 3.1)?. When I look in the Constraints Editor of the Alliance, the delay constraint shown is the same as my clock period instead of the zero I was expecting with the NODELAY constraint.. I was able to control the setup time to the same pin before with the line : NET "DATA_IN<0>" OFFSET = IN 5 ns BEFORE "SAMPLE_CLK"; in the UCF file. Could anyone please tell me how to get this working? Thanks, jakabArticle: 28915
I think the 'NODELAY' attribute refers to the 'delay element' in the IOBs; not to a *value* of routing delay. By default synthesizers include this in the signal path.

FLoorplanning and designing to the architecture will let yo do much better. I've done a large number of 4000 and derivative designs that are more than 85% full and yet run at several times the 10-20MHz clock you are citing. For example, my HDTV descrambler core is guaranteed to run at 75 MHz in any of the 4000XV parts. In the small parts, it fills most of the device. The data sheet for that design is available on my website. Kang Liat Chuan wrote: > > What is your clock frequency? I am not sure about Spartan but I have worked > on 4000xv series.

So, for making a large vector out of an array: always @( ... ) /* See below for comments on this! */ begin bar = 0; for( j = 13; j > 0; j = j - 1 ) begin bar = bar | foo[ j ]; /* Important - don't use <= !!!! */ if( j != 1 ) bar = bar << 8; end end For the other direction: always @( bar ) for( j = 1; j < 14; j = j + 1 ) foo[ j ] = bar >> ( ( j - 1 ) * 8 ); Now for the first case sensitivity list. You've got a problem there. You mistyped in your question. You probably wanted always @( foo ) not bar. Problem is verilog doesn't like an array as part of your sensitivity list. So, unless you can make bar a bank of flops ( hence the sensitivity list is @( posedge clk ), you're stuck. That last point's really a stickler. We've tried doing things like this in our code - using the array notation for easier indexing into cells like you're doing can be really convenient. But alas, we usually end up "blasting" the arrays into long wires for the whole process. We've seen all the wonderful things like this that should be fixed in verilog 2000. We're just waiting for someone to actually implement them! Regards, Mark -- Mark Curry mcurry@ti.cat.com Remove the animal from the domain to reply.Article: 28921
