Vicky, sometimes I had to wait 45 minutes of compilation, like that 1970's show.
i'm going to see your coding style, next year.
so you did not like my loops. but you don't doubt it compiled. do you?
this file is the start of the struggle. first I tested, it did not compile. I went down to older revision to compile.
in that file I made little changes and it compiled somehow.
then I've got the *.sof (I did not have time to install it in any FPGL to see the behaviour.)
the day after, I tested again, but it did not compile again.
So compilation is not deterministic. It is a stochastic process. 50% chances for compiling the same code today or tomorrow.
