How to define multi-cycle timing constraints in Lattice iCEcube2 (synplify)
In a design, I have a number of counters that have an enable that is only active every N periods of the clock signal. With only a clock...
In a design, I have a number of counters that have an enable that is only active every N periods of the clock signal. With only a clock of 200MHz in the timing constraints, the counters are assumed to run at 200MHz and timing fails. As these counters actually run at much lower speed, I know they will work. But how to convince the tools (Lattice iCEcube2) that all is OK? I am trying to add ...

Foundation 1.3/XactStep 6 dongles and licensing

I need to generate a programming file for an older XC7300 series chip using an existing Abel and/or PLD file. As far I know, only XactStep 6 and Foundation 1.3 supported those chips as Foundation 1.4 doesn't have options for them any more. I have hardware dongles for the software but no license file so a couple of questions :). 1) Do the hardware dongles still require a LICENSE.DAT file? I kno...

This is a bit of the chicken and egg thing. If you want a embed the code checksum in a code module to report the checksum, is there a way of doing this? It's a bit like being your own grandfather, I think. I'm not thinking anything too fancy, like a CRC, but rather a simple modulo N addition, maybe N being 2^16. I keep thinking of using a placeholder, but that doesn't seem

A small board with a 100QFP is being redesigned for a new FPGA due to obsolescence. Gowin makes a 100QFP device that would be a good fit, but my customer has said "no" to the 100% Chinese brand... US government customers, ya know! So now I'm looking at a BGA. I don't want to get into fine PCB design rules, so 1.0 mm ball pitch is my preference. The only devices I can find tha

I have noticed, that the categories on the list of projects https://opencores.org/projects do not unfold after clicking. That makes browsing projects impossible. Is it a problem with my browser (Firefox on Linux) or with the website? Regards, Wojtek
