FortranLint source code analysis tool simplifies the debugging and maintenance of code by identifying common problems that typically pass through a compiler. Grayboxx is a cross-platform software test automation system.

Tools for parallelization and conversion of Fortran 77 to Fortran 90: generation of new source form, removal of obsolete features, elimination or reduction of GOTOs and labels, generation of array syntax in place of loops. creation of MODULEs from COM...

Simple diagrammer for Fortran programs, by Mitchell R. Grunes.

Statically analyzes Fortran 66/77/90/95 code for syntax and semantic errors. Produces documentation like cross-references and call-tree. Validates for cross-platform conformance. [Commercial]

Flowcharting utility.

Analyzes Fortran source code and flags "hot spots, " code that is executed most often, and "cold spots, " code that is never executed. Designed for Fortran 90/95, but also works with fixed format Fortran 77 code. [Free]

FFT builds an internal representation of the function call hierarchy relations in Fortran 77 code. Several features and options allow the user to customize the generated hierarchy tree chart output and to get a large set of useful information about th...

Produces compile-time diagnostics of Fortran code using the Lahey/Fujitsu Fortran 95, Lahey Fortran 90, or Essential Lahey Fortran 90 compilers. Can show warnings, perform a Fortran 90/95 conformance check, warn about use of obsolescent features, forc...
