Magic bitstream

[guilhermerc]

We've been facing undefined behavior with the latest commits' builds. These behaviors aren't deterministic: they only occur on some controllers. Some examples are:

• Not being able to write the correction matrix;
• Not being able to write the filters' coefficients;
• Not being able to sync DCC network;
• Some correctors having "pulsating" current readings.

The main hypothesis at the moment is a lack of timing constraints which is only revealed when the design becomes more congested.

There is a bitstream which is functionally identical to master (c86a1ea) and works well, but it was built with a local commit that doesn't belong to git history anymore. I've pushed its branch and I'm attaching the bitstream to this issue.
