Hello everyone, After a long period of silence, I finally released another version of the IBIS Macro Library. It has been posted on our web site: http://www.eda-stds.org/pub/ibis/macromodel_wip/element_lib/VHDL-AMS_element_library_SMASH_test.zip http://www.eda-stds.org/pub/ibis/macromodel_wip/element_lib/Verilog-A_element_library_HSPICE_test.zip This version has numerous improvements. Here is a summary of the changes in the VHDL-AMS version: -- 2006/06/28 - Fixed "DIV" controlled sources to eliminate div/0 error -- due to execution order during first few simulation cycles. -- - Fixed the input thresholds for buffers and event triggered -- PWL sources to be more compatible with HSPICE's B-element -- threshold levels. -- - Fixed buffers and event controlled PWL sources to initialize -- properly for all possible combinations of input values. -- Also, eliminated possible glitches due to execution order of -- various simulation cycles. -- - Added BREAK statements to "DIV" and event controlled PWL -- sources. -- - Fixed V-t tables in data files for Open_*** models. -- - Added a warning to the IBIS_***_DIV elements. Please note that the VHDL-AMS test cases are still compiled with the older version of SMASH (5.6.2p2) in this release due to some problems with the latest version of SMASH (5.7.0). Here is a summary of the changes in the Verilog-A version: // 2006/06/28 - Added port direction declarations. // - Fixed a typo in the "DIV" module's analog equations. // - Added "$discontinuity" statements to "DIV" and event // controlled PWL sources. // - Removed "\" character from some of the test bench files. // - Fixed event controlled PWL sources to initialize properly // for all possible combinations of input values. // - Fixed the input thresholds for buffers and event triggered // PWL sources to be more compatible with HSPICE's B-element // threshold levels. // - Updated "state machine" of buffers and event controlled PWL // sources to follow the same algorithm as in the VHDL-AMS // version. // - Added a warning to the IBIS_***_DIV elements. I hope that with these changes we will have a more robust library. Also, as far as I am concerned, I think the library is pretty much done (other than adding the description to each element). Please let me know if there is a need to fix any bugs (I hope there are none), or add any features, or bring it up for discussion in one of our meetings. Thanks and enjoy!
