When compiled with Precision + SpDE, the bitfile works fine in hardware, but the bitfile created by ql-symbiflow doesn't. Siva can provide more details on the failure, but it appears that the I2S receiver occasionally adds an extra bit to the received data. I can't tell if this is a functional issue or timing.

The issue with Symbiflow is the data collected via I2S may show wrong values.
