AFAIK you get the free Modelsim version only for Windows(32bit) from Xilinx. The free suite for Altera (Webedition) seems to be windows only, linux requires licensing. Several parts of the design suites ISPLever are Windows only, Programming Actel FPGAs is only possible using Windows... The versions of ISE I used showed not that good performance on linux. Quartus Linux is only titled Beta, never worked with, but guess the same here. Actel Designer has bad performance on Linux as well. bye Thomas

Modelsim ASE is included with Quartus under Linux at no extra cost. Altera has to pay royalties for their Mainwin library hence they will not give it away, but they have a Qt based GUI now so I would expect to see a free Quartus Webedition for Linux soon. The free Modelsim versions are running at a reduced speed under both Windows and Linux. On the other hand the Synopsys VCS simulator is not available for Windows. > Several parts of the design suites ISPLever are Windows only, > Programming Actel FPGAs is only possible using Windows... Does that mean you can't generate a SVF file either? > The versions of ISE I used showed not that good performance on linux. Hmm. I don't use the GUI that much (other than for floorplanning and signaltap/chipscope) so most of my builds are done in batch and I have not noticed any reduced performance under Linux. > Quartus Linux is only titled Beta, never worked with, but guess the > same here. Quartus for Linux is not beta. The recently released Qt GUI front-end is beta, but not the regular Quartus version. The performance of Linux (Quartus 9.x) is the same as for Windows.

Solaris on x386/AMD64 was never supported. I don't follow Xilinx all that closely but I think their situation with regard to Solaris support is identical to Altera's.

You can generate a programming file under linux. But you can't use the programmer (and programmer SW) neither for Antifuse nor for Flash- based. The core generator for more complex cores(PCI and so on) also requires Windows. And as already stated, the actual version of designer under Linux is to slow to do reasonable layout/floorplan of complex designs. bye Thomas

I've used VCS since it was first released by Chronologic until two years ago, since then I've used ModelSim and I really miss VCS... >> > Several parts of the design suites ISPLever are Windows only, >> > Programming Actel FPGAs is only possible using Windows... >> >> Does that mean you can't generate a SVF file either? > > You can generate a programming file under linux.

It's probably a tough job for the smaller companies to develop multi-platform software since they don't have the resources that Xilinx and Altera has. However, it could have been interesting if some of the smaller vendors would open source their software to get some community help. But some of their software might be based upon some commercial packages outside their control, which makes it impossible unless it's re-written.
