Working on the command line in a Linux shell can be tricky at times. A frequent source of frustration is that tasks which are trivial with a graphical desktop environment can be seemingly much more difficult to achieve on the command line. For example switching between multiple running applications only requires one or two mouse clicks on a graphical desktop, but demands more arcane knowledge to do it on the command line.

In advanced FPGA systems which require different clock frequencies for different parts of the design, there is often a shortage of global clock buffers. Often several of the clocks are related (see below) and it becomes possible to use a single clock plus several clock enable signals, instead of several dedicated clocks. This article tries to shed some light on the impact these two alternatives can have on an FPGA system.
