Correct Answer: A blocking assignment is one in which the statements are executed sequentially, ie, first statement is executed and variable is assigned a value then second is executed and so on A non blocking assignment is one in which statements occurs conturrently, only non blocking assignments should be used in sequential circuit eg initial begin a=b; //blocking c<=a; //nonblocking d=c; // blocking end In this example firstly the value of b is assigned to a and this value is assigned to c only after execution of first statement the second and the third statements are executed simultaneously, ie value a ais assigned to c and previous value if c is assigned to d

Correct Answer: For D latch: always@(enable) q<=d; For D flip flop: always@(opsedge clock) q<=d;
