Patent ID: 8136168

Claim:
An encryption and decryption system for integrated circuit (IC) design with design-for-manufacturing (DFM), comprising: a public key in non-transitory computer readable storage configured to be provided to an IC design tool vendor for encoding vendor design information into an IC design tool; a decryption module configured to be embedded in the IC design tool in non-transitory computer readable storage, wherein the decryption module includes a static library having a decryption application program interface; an encrypted DFM data in non-transitory computer readable storage configured to be provided to an IC designer authorized for utilizing the encrypted DFM data, wherein the DFM data comprises manufacturing data including lithography process check (LPC) data, chemical mechanical polishing (CMP) data, and critical area analyzer (CAA) data, wherein the DFM data comprises DFM advisories including action required rules integrated with a design tool, recommend rules integrated with the design tool, and guidelines provided to a designer for implementing IC design; a private key in non-transitory computer readable storage configured to be provided to the IC designer for decrypting the encrypted DFM data in the IC design tool, wherein the private key is synchronized with the static library through version control, and further wherein the decryption module checks a version number and an expiration date of both the static library and the private key to enable or disenable decryption of the encrypted DFM data; and DFM utilities in non-transitory computer readable storage to be integrated into the IC design tool for providing corrective actions to the IC designer utilizing decrypted manufacturing data and DFM advisories.
