A circuit for implementing a plurality of circuits on a programmable logic device, the circuit comprising a first circuit implemented on a first portion of the programmable logic device; a second circuit implemented on a second portion of the programmable logic device; and a control circuit coupled to the first circuit and the second circuit, the control circuit providing isolation between the first circuit and the second circuit. While the first circuit and the second circuit may comprise redundant circuits implementing a common function, the circuits may also comprise circuits which must be isolated, such as an encryption circuit and a decryption circuit implementing a cryptographic function. A method for implementing a plurality of circuits on a programmable logic device is also disclosed.
