Example text

Mentor is the current leader with its Catapult synthesis; Cadence has created its own CtoSilicon technology. But Synopsys, who has synthesis running through their veins, has no real high level synthesis product (and, unless they are doing it with people who are unknown in the field, don’t have one in development). Synopsys does have FPGA DNA through the acquisition of Synplicity. My opinion is that once it becomes clear which HLS company is going to win, 57 EDAgraffiti Synopsys will likely acquire them and for a serious price to complete their FPGA offering.

Of course a cynic would say that’s just because Macs are so expensive, but these are the computers used by professional programmers, graphic designers and musicians. It is true that the average ASP of a Windows PC was $515 but for Mac it was $1,400. I would guess the profit is much more than 3 times as much per Mac as per PC. So those “laptop hunters” ads have it correct. You can get a PC for much less than a Mac, but it’s not really an equivalent machine. Apple has gone from 60% of the over $1,000 market at the start of last year to that 91% number now.

Other businesses don’t move so fast. Waiting for the big guys to develop the technology is usually the safest approach. This startup-centric world may be changing as the importance of integration increases and so the importance of point technology diminishes. I spent years at Compass Design Automation with a fully-integrated toolset that was very productive. But customers would only buy “best-in-class point tools” and do all the integration themselves. We were selling an engine when people wanted to buy their own ignition system, their own fuel-injectors and make the wiring harness themselves.
