Projects / ASCO


The ASCO project aims to bring circuit optimization capabilities to existing SPICE simulators using a high-performance parallel differential evolution (DE) optimization algorithm. It supports Eldo, HSPICE, LTSpice, Spectre, Qucs, and ngspice.

Recent releases

  •  21 Jul 2013 11:01

    Release Notes: Initial support for the ngspice simulator. Corrects a memory leak in parallel mode. Minor bugfixes in the 'log' and 'postp' tools.

    •  27 Feb 2012 19:25

      Release Notes: This release makes the "postp" tool better support Spectre, supports Spectre in the "alter" tool, support the IEC 60063 preferred number series for resistors, capacitors, and inductors (E3, E6, E12, E24, E48, E96, and E192), and cleans the code.

      •  01 Aug 2010 11:39

        Release Notes: A multiprocessor optimization algorithm message truncation error related to the MPI_SCATTERV function was corrected. The load balancer implementation was corrected. The RF module better supports Spectre. Support for LTspice and Spectre was added in the "postp" tool. The code was cleaned up. Minor improvements were made.

        •  26 Mar 2007 14:59

          Release Notes: Improvements were made in the RF module functionality. Support was included for logarithmic search space for the existing variables. Code refinements and bugfixes were made.

          •  09 Oct 2006 13:38

            Release Notes: This release adds a retouched load balancer, emulation of local optimization using the parallel DE optimizer, more patches to compile with MinGW32, and some minor enhancements.
