Abstract: A library test circuit for verifying functions of a plurality of standard cell library logic cells includes a core module including a plurality of standard cell library logic cells, each logic cell having a predetermined number of input vector combinations, the core module outputting test result signals according to a standard cell library; a first switch bank for outputting a first input signal to the core module so as to select cell identifiers corresponding to respective logic cells; and a second switch bank for outputting a second input signal to the core module so as to select pattern identifiers corresponding to input vector combinations of each logic cell.

Abstract: Disclosed is an integrated circuit having an encryption core. The integrated circuit includes an encoder configured to encrypt an input plaintext using a first cipher key to produce a ciphertext, a decoder configured to decrypt the ciphertext using a second cipher to produce a decrypted plaintext, and a comparator configured to compare the input plaintext with the decrypted plaintext to produce a comparison result.
