There seem to be a spate of new FPGA companies coming out. The road block to new FPGA companies has always been two things, patents and software... a nd maybe software patents. lol
So what has changed?
For sure FPGAs have been around long enough that many of the basic patents have expired. The LUT/FF combo that is the basis for all FPGAs has been av ailable for some time now. Has some other fundamental patent expired more recently to allow these companies to rise from the primordial soup?
Then there is the effort required to develop the software to design these p arts. I suppose with the various third party tools that cost has been redu ced compared to starting from scratch, but it still has to cost a lot unles s they are mimicking other, existing devices which I don't think they are d oing, are they?
In the last 20 years I don't know that I've seen any new FPGA companies oth er than mergers. Now there are at least four newcomers to the business. W here/how did this happen?
