Has anyone worked with the Lattice Semiconductor ECP2M series of FPGA? Were the parts easy to get? Also, how is the ispLever design software from Lattice? I've worked exclusively with Xilinx FPGAs and am looking for some feedback about what else is out there. My particular interest developed in the Lattice ECP2M because I need a FPGA/SERDES combo and the price for the ECP2M seems unbelievable compared to their competitor's equivalent FPGAs. So, I'm thinking something must be wrong? Thanks, Colin

My personal belief is that they targeted the right mix of features at the right time to hit big holes in the competitions' low-cost portfolios. Given reasonable cost of dedicated high-speed devices out there, I just don't understand why SerDes *should* cost as much as is implied by other FPGA vendors. Another aspect: Lattice is probably hungrier than the big guys to get those design wins to establish themselves as a strong player. I hope we both get a chance to work with the ECP2Ms. - John_H

HI Colin, A couple of weeks ago, one of the local FAE's told me that only the biggest device/package (ECP2M100-F1152) is not available in production. This means that you should be able to get parts quickly. I have personally worked with ECP2M20-F256 on a video board (HD/SD-SDI) and I haven't encountered big issues. I got it to work in some 2 weeks time. And yes you are right, the price of the ECP2M family vs. competitor's equivalent IS incredible. The price was cut by two. Success with your implementation.

Colin, If you email me directly what size ECP2M part you are considering, and if you work with a distributor or FAE (who is your contact for Xilinx), I will have someone get back to you. Austin

Austin, Does that mean Xilinx has something in the pipeline?

I find that the Lattice approach is much more upfront - its all on the web and the distribution is used for box shifting (which is about all they are capable of (on a good day)). My heart sinks when a semi company says 'contact the disti of FAE' - in the case of small users like me and the big distributors like X and A use it means 'prepare to plumb new depths of ignorance and/or bad service' For a while X had only one distributor in the UK and that was truly awful. There are 2 now but my limited contact with the new one has not been strong on surpise and delight. Michael Kellett

The 60K LE device is $262.50 from Arrow, about the same as the 70K device from Lattice. The SERDES in the Lattice device looks better (and there are more of them), but Altera's synthesis tools are better. The free web edition software supports this device. I know they support x4 PCIe, if that's why you need the SERDES. -- /* jhallen@world.std.com AB1GO */ /* Joseph H.

MK, Sorry to hear you feel this way. I would hope that contacting your Xilinx distributor would result in useful and helpful information. If not, we would certainly like to know. "Being small" has many disadvantages, but I have to say that many FPGA sockets are created by 'small' businesses. To that end I would hope that our distributors are doing the job we expect them to do by providing you with the services you require. Sounds like that did not happen. Perhaps this is something we should be aware of? As always, Peter an I stand ready to listen (and act). Austin
