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.
- "MISRA" and the triangle logo are registered trademarks of HORIBA MIRA Ltd, held on behalf of the MISRA Consortium.
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]

|---|---|
| Required | 67/93 |
| Advisory | 19/34 |
| Total | 86/127 |
