The Various types of delays in

VHDL are :1. Delta delay - In VHDL simulations, all signal assignments occur with someinfinitesimal delay, known as delta delay. VHDL uses the concept of deltadelay to keep track of processes that should occur at a given time step,but are actually evaluated in different machine cycles .A delta delay is aunit of time as far as the simulator hardware is concerned, but in thesimulation itself time has no advance. Technically, delta delay is of nomeasurable unit, but from a hardware design perspective one should thinkof delta delay as being the smallest time unit one could measure, such asa femtosecond(fs). 2. Inertial delay - The inertial delay causes the pulses less than specified delayto get suppressed & will not propogate these pulses to change the output.The inertial delay model is specified by adding an after clause to thesignal assignment statement. Inertial delay is basically a default delay,i.e it's a component delay. 3. Transport delay - Tranport delay adds the propogation delay to the signal.The transport delay model just delays the change in theoutput
