Do178Builder is a documentation tool used throughout the software/hardware development effort, helping to produce the DO-178B/254 documentation much less painfully. A major obstacle to creating airborne products, for smaller developers, is the necessity to qualify the software per RTCA/DO-178B, or hardware per RTCA/DO-254. Without this qualification, airborne products cannot be deployed.
CUT is a unit-testing framework for C, C++, and Objective-C. Unlike other unit testing tools, CUT doesn't strive to be an SUnit clone. It automates a lot of the drudge work often encountered when using other unit testing packages for the C family of programming languages. CUT may also be used to unit-test assembly language software in some circumstances.
TIMES is a tool suite designed mainly for symbolic schedulability analysis and synthesis of executable code with predictable behaviors for real-time systems. Given a system design model consisting of a set of application tasks (required to meet mixed timing, precedence, and resource constraints), a network of timed automata describing the task arrival pattern and a preemptive or non-preemptive scheduling policy, TIMES will generate a scheduler, and calculate worst-case response times for the tasks. The design model may be further validated using a model checker and then compiled to executable C-code.
simena-io is a Linux tool written in Perl and designed to show ethernet interface statistics in bits/second and packets/second in real time. It requires at least Linux kernel 2.2 and Perl 5. It does not require a root account. There is only one command parameter: the refresh rate in seconds. If no parameter is provided, simena-io will refresh every 2 seconds by default. Detailed documentation can be obtained by running "perldoc simena-io".
