Overview
Description
SQMlint is a tool to inspect C source codes according to MISRA C rules (Note1). Because SQMlint assists developers in source code review through automatic inspection, it helps to develop high-quality C source codes efficiently. Furthermore, because problem codes can be detected by only adding compile options, the user can correct problem codes as easily as when correcting compile errors.
Note
[About MISRA C]
- MISRA C refers to the guidelines for the use of the C language in vehicle-based software that have been created by the Motor Industry Software Reliability Association (MISRA), a nonprofit organization for software reliability that was organized primarily by the automotive industry. These guidelines stipulate 127 rules relating to the program description in C language, which are referred to as MISRA C rules.

The MISRA C rule checker is being supported with a compiler option by the following compilers professional editions.
- Compiler Package for RL78 Family (CC-RL)
- Compiler Package for RX Family (CC-RX)
- Compiler Package for RH850 Family (CC-RH)
Without buying a product separately, the MISRA C rule checker can be used.

Additional Details
Functions
MISRA C rule inspection during compilation
Source codes can be inspected against MISRA C rules by only specifying options when compiling the source files. There is no need to build an inspection-purpose environment.
Adaptable to special options of the Renesas C compiler
If special options such as one that handles the double type as float type are used, C source codes are inspected by taking the effects of those options into consideration.
Usable in the Renesas integrated development environments, High-performance Embedded Workshop and TM
You can make a tag jump in Renesas integrated development environment HEW or TM based on the output results and correct the C source codes on the spot. Therefore, deviations from MISRA C rules can be corrected in the same way as when correcting compile errors.
Inspection results output in CSV format (Report file)
The inspection results are output as report files in CSV format usable in spreadsheet software, and can be analyzed more efficiently by using bundled utilities.
[Number of MISRA C Rules that can be Inspected]
| Rule classification | Number of rules inspected (number of rules inspectable by SQMlint / total number of rules) |
|---|---|
| Required | 67/93 |
| Advisory | 19/34 |
| Total | 86/127 |
