Add an option (-p) to force use of SB_PLL40_PAD

2021-02-05T15:35:50+00:00

When a clock is applied to a dedicated clock pin, SB_PLL40_CORE is no longer the correct primitive to use. Also the name of the clock input must be PACKAGEPIN (rather than REFERENCECLK)

Add iteration over list of frequencies for best solution

2019-12-30T23:06:59+00:00

This patch adds support for icepll to try multiple input frequencies to find the best crystal for the desired output frequency. The values tested comes either from a specified file using-B, or from a default set of frequencies from Mousers "normally stocked" crystal oscillators.
