ASCO

ASCO aka A SPICE Circuit Optimizer is an open source project that aims to bring circuit optimization capabilities to existing SPICE simulators, using a high-performance parallel differential evolution (DE) optimization algorithm.

At the moment, ASCO includes out-of-the-box support for HSPICE (R), Eldo (TM), LTspice (TM), Qucs, ngspice, and Spectre (R).

With ASCO you can reuse and optimize an existing circuit, fully redesign a new circuit described in a SPICE netlist, easily explore a new operating point, migrated a working design to a more complex semiconductor technology, increase the yield and robustness of an already designed circuit, and much more.

What is new in this release:

• Initial support for ngspice simulator.
• Corrected memory leak in parallel mode. Minor bug fixes in 'log' and 'postp' tools.

What is new in version 0.4.7:

• Corrected multiprocessor optimization algorithm message truncation error related to MPI_SCATTERV function.
• Corrected load balancer implementation.
• RF module better supports Spectre.
• Support for LTspice and Spectre in the 'postp' tool.
• Code clean-up and minor improvements.
