TBL verify check for CFE_PLATFORM_TBL_MAX_SNGL_TABLE_SIZE does not match documented description

[irowebbn]

Describe the bug

According to the desciption in the platform config header, the value for CFE_PLATFORM_TBL_MAX_SNGL_TABLE_SIZE) must be "small enough to allow for #CFE_PLATFORM_TBL_MAX_SIMULTANEOUS_LOADS number of tables to fit into #CFE_PLATFORM_TBL_BUF_MEMORY_BYTES." (see

cFE/cmake/sample_defs/example_platform_cfg.h

Line 1369 in d6e6107

** The cFE does not place a limit on the size of this parameter but it must be

).

However, in modules/tbl/fsw/src/cfe_tbl_verify.h , the logic for checking this appears to be off by one:

#if ((CFE_PLATFORM_TBL_MAX_SIMULTANEOUS_LOADS + 1) * CFE_PLATFORM_TBL_MAX_SNGL_TABLE_SIZE) > \
    CFE_PLATFORM_TBL_BUF_MEMORY_BYTES
#error Shared buffers and table of size CFE_PLATFORM_TBL_MAX_SNGL_TABLE_SIZE cannot be greater than memory pool size of CFE_PLATFORM_TBL_BUF_MEMORY_BYTES!
#endif

This leads to compliant configuration values failing to compile.

To Reproduce
Steps to reproduce the behavior:

1. Edit CFE_PLATFORM_TBL_MAX_SNGL_TABLE_SIZE and CFE_PLATFORM_ES_MAX_BLOCK_SIZE to be a large value, such as 196608
2. Edit CFE_PLATFORM_TBL_BUF_MEMORY_BYTES to be equal to CFE_PLATFORM_TBL_MAX_SNGL_TABLE_SIZE * CFE_PLATFORM_TBL_MAX_SIMULTANEOUS_LOADS (in this case 786432, for the default simultaneous load value of 4).
3. Try to compile
4. See error
