may be related, may be not - this is 65nm (around 700mhz top speed) and 40nm (around... 1.2ghz top speed if you're very lucky and have a decent design). "multivendor" program, basically you chuck a whole bunch of customer's designs onto a single wafer, absolutely nobody expects to get very many actual working ICs out of it, but the cost of a single wafer (bear in mind that 16 wafers have to be made simultaneously, total cost around $250k or that order, for 40nm) is subdivided amongst many many people. end result: relatively cheap prototype grade ICs. the bit about conversion from FPGA... *shudder* that's truly dreadful, to not bother with the conversion from FPGA layout to a proper IC layout, just do like a "hard copy" of an FPGA, but given that the tools can cost $250k *PER WEEK* to rent (not buy) that's hardly surprising. anyway all looks very interesting. l. --- crowd-funded eco-conscious hardware: https://www.crowdsupply.com/eoma68 On Fri, Nov 18, 2016 at 4:57 AM, Luke Kenneth Casson Leighton <[email protected]> wrote: > --- > crowd-funded eco-conscious hardware: https://www.crowdsupply.com/eoma68 > > > On Thu, Nov 17, 2016 at 9:09 PM, Paul Boddie <[email protected]> wrote: >> On Thursday 3.
