Finite state machines are widely used in digital circuit designs. Generally, when designing a state machine using an HDL, the synthesis tools will optimize away all states that cannot be reached and generate a highly optimized circuit. Sometimes, however, the optimization is not acceptable. For example, if the circuit powers up in an invalid state, or the circuit is in an extreme working environment and a glitch sends it into an undesired state, the circuit may never get back to its normal OPERATING condition.

Semiconductor memory, card readers, microprocessors,disc drives, piezoelectric devices and digitally based systemsfurnish transient loads that a voltage regulator mustservice. Ideally, regulator output is invariant during a loadtransient. In practice, some variation is encountered andbecomes problematic if allowable OPERATING voltage tolerancesare exceeded. This mandates testing the regulatorand its associated support components to verify desiredperformance under transient loading conditions. Variousmethods are employable to generate transient loads, allowingobservation of regulator response

項目描述: Env_audit is a program that ferrets out everything it can about the environment. It looks for process IDs, UID, GID, signal masks, umask, priority, file descriptors, and environmental variables. It comes with test configurations for anacron, apache, atd, crond, GDB, inittab, logrotate, PHP, pppd, procmail, rsh, rxvt, sendmail, SSH, stunnel, sudo, xinetd, and xterm. env_audit是一個搜索有關(guān)環(huán)境的所有東西的程序。它查詢進(jìn)程IDs,UID, GID,信號掩碼,umask,優(yōu)先權(quán),文件描述符,和環(huán)境變量。它提供了用于anacron, apache, atd, crond, GDB, inittab, logrotate, PHP, pppd, procmail, rsh, rxvt, sendmail, SSH, stunnel, sudo, xinetd, 和xterm的測試配置。 類別: Development Status: 5 - Production/Stable Environment: Console (Text Based) Intended Audience: System Administrators License: GNU General Public License (GPL) OPERATING System: POSIX Topic: Security

Bochs is a highly portable open source IA-32 (x86) PC emulator
written in C++, that runs on most popular platforms. It includes
emulation of the Intel x86 CPU, common I/O devices, and a custom
BIOS. Currently, Bochs can be compiled to emulate a 386, 486,
Pentium, Pentium Pro or AMD64 CPU, including optional MMX, SSE,
SSE2 and 3DNow! instructions. Bochs is capable of running most
OPERATING Systems inside the emulation including Linux, DOS,
Windows 95/98 and Windows NT/2000.
Bochs was written by Kevin Lawton and is currently maintained by
the Bochs project at "http://bochs.sourceforge.net".
