At first, it’s great. Looks like a race car, good performance, nice receiver, rechargeable on the fly etc. Then, something feels off… something uncomfortable. I turn the mouse over and the fatal flaw. The sensor isn’t placed at the center of the mouse but almost under your thumb… Continue reading

Heed the warning and it will save you days in debugging with random error appearances that simply won’t go away with any numbers of repairs and recompilations because you’re simply not recompiling your circuitry!
On designing FPGAs or CPLDs on Altera with their primary software designer, the Quartus, a compilation of a multi-level circuit will result in the compilation of only the topmost level. In order a change in say the bottom level, you would have to compile the bottom level, create new module symbol, go to the next level, update the symbol, compile that level, create module symbol and move one level up until the top which obviously makes it extremely ridiculous to debug.
