EMF Validation Builder is an Eclipse plugin that automates the validation process at the time of saving. This means that resource problem markers are up to date as soon as you save your model. A dependency table is maintained, which allows the validation process to be re-run when necessary. In particular, the tool can be directly used with ECore model files.
Sigasi is an intelligent Eclipse- based development environment (IDE) for the VHDL language. It contains an ultra-fast VHDL parser and compiler that runs transparently in the background. At any given moment as you make modifications, the tool fully understands the design in terms of VHDL concepts. It allows you to write code faster by providing intelligent code completion, instant error reporting, intelligent navigation, mouse-over descriptions, a hierarchy browser, version control, issue and time tracking, and project and code templates.
