SDF Report Generation Methodology for Digital Delay Lineswithout Simulations

Abstract

In this paper a methodology of report generation for Digital Delay Lines (DDL) is presented. The mentioned approach is based on DDL report generation using Perl scripting without any Spice and Standard Delay Format (SDF) simulations. The need for this kind of approach is since generation of the DDL spreadsheets using Spice simulations brings to a great loss of time, because parallel to the increase of the number of elements, the extract netlists are also being increased. The presented approach saves more time compared to SDF simulations as well, because for large designs SDF files have very big sizes, which causes increase of machine resources and time for parsing and back-annotation of that SDF files. The methodology suggested in this paper uses the data of DDL SDF files to generate reports neglecting the parsing and back-annotation of SDF files.
