You know, for those frivolous activities like finite element magnetics, deep-silicon IC design, FPGA design, and the like.
Strange you should mention it...
FPGA Design Software supports high-speed DDR interfaces.November 18, 2009 - Allowing design of DDR interfaces for LatticeECP3(TM) FPGAs, ispLEVER® FPGA design tool Suite v8.0 features automatic interface code generation and timing analysis functions. Program includes GNU compiler v4.3.0, which allows flexible code deployment options; Tri-speed MAC IP that can be interconnected into high-throughput configurations; and SPI Flash Controller that allows read and write access. It supports Red Hat Enterprise Linux v5.3, Unix, and Windows.
Of course, you are aware that Mac OS X is a fully certified UNIX™, one of the four so qualified, and fully capable of running all of the UNIX IC design software out there... and there are a lot of Macs in use at Lawrence Livermore National Laboratory for even more complex usages.
Lattice JUST RELEASED, if you notice the date. Of course, the dominant platform in the market, Xilinx, isn’t supported on the Mac...
And what about integrated schematic capture and PCB layout?
Or parametric 3D CAD?
See, there are actually applications and entire industries that don’t run on the Mac platform. And thus, for those people, a Mac is a BAD CHOICE. Can you accept that?
