摘要： A method of automatically analyzing RTL code includes receiving as input RTL code for an integrated circuit design. An RTL platform is selected that incorporates design rules for a vendor of the integrated circuit design. The design rules are displayed from the RTL platform on a graphic user interface. A number of the design rules are selected from the graphic user interface. An analysis is performed in the RTL platform of the RTL code for each of the selected design rules. A result of the analysis is generated as output for each of the selected design rules.
