From Jeremy:

Btw the verilog model of the dffsr_cell is wrong - it implies S and R only have effect on their rising edges where in fact they have level sensitive effects ie if S is high it holds the output at 1 irrespective of the clock and data - and the S and R both being high should give an X output (undefined) - I think
