项目描述

Ngspice is a mixed-level/mixed-signal circuit simulator based on three open source software packages: Spice3f5, Cider1b1, and Xspice. Spice3 is the most famous and widely used circuit simulator. Cider is mixed-level simulator that includes Spice3f5 and adds DSIM, a device simulator. Cider couples the circuit level simulator to the device simulator to provide greater simulation accuracy (at the expense of greater simulation time). Xspice is an extension to Spice3 that provides code modeling support and simulation of digital components through an embedded event driven algorithm.

rework-21

几个错误已得到修复，提高稳定性和可靠性。一个处理与其他模拟器兼容模式加入。的BSIM 4已更新到4.6.5版本。 BSIMSOI已更新到版本4.3.1。从kspice传输线进行了更新和纠正。乙来源是同一个的PWL功能改善，但“赫兹”，“时间”和“脾气”变量，而另外一个三元函数的加法。的PWL来源改善，重复参数相关（r =值）和一个延迟参数（运输署=值）。

Several bugs have been fixed, improving stability and reliability. A compatibility mode for dealing with other simulators was added. BSIM 4 was updated to release 4.6.5. BSIMSOI was updated to version 4.3.1. Transmission lines from kspice were updated and corrected. B sources were improved with a PWL function, the addition of "HERTZ", "time" and "temper" variables, and the addition of a Ternary function. PWL sources were improved with a repeat parameter (r=value) and a delay parameter (td=value).

rework-18

在Tclspice模拟器图书馆已经并入ngspice。新的方案已经实施：简短，上市，自动停止，和规模。支持。lib文件引入了。 。措施的声明：平均，整台，有效值，最大值，最小值，延迟和param。 。全球性的发言表示支持。为内联成网表的功能。函数宏。该numparam图书馆已得到改进，完全支持参数化网表。 BSIM模型的群组功能。新的多输入门电压控制电压源使用XSPICE扩展。
标签: Major feature enhancements
The Tclspice simulator library has been merged with ngspice. New options have been introduced: brief, listing, autostop, and scale. Support for .lib files has been introduced. .measure statements: avg, integ, rms, max, min, delay, and param. .global statement support. .func macros for inlining functions into netlists. The numparam library has been improved to support fully parametrized netlists. BSIM model binning. New multi-input gate VCVS using XSPICE extensions.

rework-16

对大部分漏洞已经被修复，所以ngspice更稳定，特别是xspice扩展，子电路处理和numparam库。语法已经扩大，最终的行注释允许。阿“。全球”卡斋添加到确定全球节点。它可以定义就行，例如电阻训练班。该editline库可以代替的ReadLine。 ngspice目前工程进展（xspice）在Windows中使用MinGW的/ MSYS。
标签: Minor feature enhancements
Most of the bugs have been fixed, so ngspice is
more stable, especially the xspice extension,
subcircuit handling, and numparam library. The
syntax has been expanded, allowing for end-of-line
comments. A ".global" card has beed added to
define global nodes. It is possible to define TC
for resistors on the instance line. The editline
library can be used instead of readline. ngspice
now works (with xspice) on Windows using
MINGW/MSYS.
