sequential and combinational

[alangs]

can any one plz tell me the exact difference between sequential logic circuit and combinational logic circuit with some verilog code.

The main difference is that a sequential circuit is clocked while a combinational circuit is not.
For example check out this example of **broken link removed** for a sequential circuit. Check out this example of a **broken link removed** for an example of a combinational circuit.

Hello Alangs,

Combinational CIrcuit : The outputs of the circuit at any instant of time are entirely dependent upon the inputs present at the time.

Sequential Circuit: It consists of combinational circuit + memory element to form a feeback path. The binary information at the memory elements defines the state of the sequential circuit.
So, the outputs at any time instant are function not only of inputs but also of the prsent state of the emeory elements.

I guess you should read the following book "digital design", 4th edition ebook by Morris Mano

Best wishes,
