The protein decay-accelerating factor (DAF) acts to inhibit complement by displacing C2a from the C4b2a complex. In addition, C3bBb is rapidly disrupted by the action of DAF. As a result, which complement pathway(s) is/are directly inhibited? O Classical O Alternative O Classical and lectin O Lectin O Classical, lectin, and alternative

1. (10 points): Which of the following identifiers are not legal basic identifiers? Why? port3, Reset_Pulse, 24_hour, iftrue, data_strobe, test[5], begin, A6bus, A_B_C, now_, VHDL 2. Consider the following concurrent signal assignment statements: A $\leq$ B or C after 6 ns; D $\leq$ A nand mux after 8 ns; Does the order of these statements matter? Why? How does this differ from assignment statements in conventional procedural programming languages? (5 points) Suppose initially (at t=0ns), B='1', C='0' and mux='1'. What will be the values of A and D at time t=20ns? At time t=100ns, an event on B causes it to go from '1' to '0'. Describe the sequence of events (signals, values and times) that will follow from this transition on B. (5 points) What if there were no explicit delay clause in both of the above statements (in other words, the delay of each gate was zero). What would the event sequence (signals, values and times) look like now? Would you get a different logical result? (5 points)
