Many post-synthesis simulations fail

[wfjm]

Many post-synthesis functional and especially post-routing timing simulations currently fail due to startup and initialization problems. Cause is MMCM/PLL startup, which is not properly reflected in the test bench. Will be resolved in an upcoming release.

Note: behavioral simulations work fine, and the real FPGA too.
