Suppose you have a synchronous sequential circuit whose clock has a cycle time of 900 ps (i.e., Te = 900 ps). The flip-flops have the timing characteristics given in Table 1 below. What is the minimum contamination delay of a combinational circuit between two registers? Give your answer in number of picoseconds (ps). For example, if your answer were 800 ps, you would write 800.
