PCB design software for Linux machine

Hi,

We currently have SPB16.6 Installed on our Linux server, However, it seems inconvenient to use:

1. The design environment isn't integrated; the user has to first run Allegro HDL to create schematic, then run the PCB editor to create layout. This meens that forward/back annotation is inconvenient.

2. Also, there seems to be a lot of set-up to be done before actual design work starts.

3. Lastly, for every foot-print or library edit there are separate tools that must be loaded separately and break the design flow.

Is there any way to use SPB as an integrated design environment? If not, what other alternatives do we have? Am I missing something?

Since my group's research focus is IC, our PCB needs are usually simple (~2-4 layers, High freq but not to dense designs)

Thanks ahead,

Matan
