New Built-in Dichotomic Search Algorithm in Smartspice

January 2, 1999

General purpose dichotomic search method is often requested by designers when they want to find a specific element (voltage, current, parameter value ...) in an already sorted set. For example, a typical problem that makes extensive use of this kind of algorithm is the computation of setup and hold time for cell characterization. This problem was already discussed in two articles [1] and [2] and a solution was proposed with the use of the SmartSpice Script Language and .MODIF statement.

Expert Expanded with Client-Server Project/Library Management

December 1, 1998

The Expert layout processor v.2.0 introduces a client-server system for managing large projects in multiuser design environments. This system is a significant improvement and enhances productivity by providing concurrent access to the same design data by several designers while maintaining data integrity and ensuring security for intellectual property.
