Installation

WRspice Generation 3 has built-in capability for automatically checking for update availability, and for actually downloading and installing updates. After installing for the first time, the passwd command should be run to enable these features.

Compatibility Improved

Many changes were made to provide direct support for the IBM_9SF foundry PDK models and similar, which make extensive use of HSPICE-specific constructs and features. Keyword and comment handling have been extended to support syntax used by other simulators.

MOS Level 54 Added

The level 54 MOSFET model was added, for IBM/HSPICE compatibility. This is the stock Berkely BSIM4.3.0 model, without HSPICE extensions. There is a collection of test files for this model, using the IBM libraries and Berkeley samples, available in the examples directory. The newer BSIM4.4.0 model is still available as level 14.

Expression Syntax More Flexible

The syntax accepted by the expression parser is now more flexible and C-like, but 100% backward compatible. Ternary conditionals

expr1 ? expr2 : expr3

are now recognized. A number of new math functions were added, including new random generators consistent with HSPICE.

Improved Parameter Handling

Parameter (.param) handling was enhanced to provide quicker circuit loading when large numbers of parameter definitions are present. User-defined functions can now be defined in .param lines.

Much More

Error logging to a file is now supported in graphical mode. Plot windows can now display up to 18 traces in "separate" mode, up from 10 in earlier releases. The code that handles the initial input file parsing was rewritten, to better handle both parameter and shell expansion. Many more incremental improvements were made, see the release note for more information.
