| | 2009-12-31 www.eetimes.com Toni McConnel | | | LDRA has integrated the LDRA tool suite and Microchip Technology's MPLAB PIC18, PIC24 and dsPIC32/33 tool chains. Leveraging the scalability of its components, LDRA can scale the LDRA tool suite down to run application code on small processor footprints, enabling very low-cost and low-power PIC processors to be used in DO-178B qualified environments.
Microchip's PIC18, PIC24 and dsPIC32/33 families are 8- and 16-bit microcontrollers, specifically designed to provide optimal functionality in a low-overhead design. The scalability of LDRA's components enables LDRA to offer full tool suite functionality with kilobytes of RAM and tens of kilobytes of ROM. By hooking into the PIC serial I/O ports, developers gain identical output across each of these PIC families.
Similarly, the LDRA tool suite fully integrates with the PIC tool chains, allowing for compilation, linking, and programming in the PIC tool chain environment.
Despite Microchip Technology's wide range of compilers and processors, LDRA is able to abstract the tool suite uniformly to the user. Flexible licensing enables this breadth of integration to be fully covered with LDRA's Target License Package. End users gain full use of graphical test planning and automatic test vector generation tools in the target environment, reducing the need for programmers and testers to have an in-depth knowledge of the extensive differences represented by each PIC platform.
The LDRA tool suite integration enables developers to use very low-cost, low-power PIC processors in DO-178B qualified environments. Even though Microchip Technology follows a non-ANSI standard C implementation, LDRA is able to analyze and run code on the target and extract the results to create reports identical to those from a more fully featured development environment. With access to this level of investigation, developers can design in Microchip Technology's low impact PIC processors for qualification environments such as DO-178B level A or analogous medical and industrial qualification environments. |
