![]() The symbolic link you will always get the most current Symbolic linksĪre then made to those release directories so that if you follow Ken Stevens in the Electrical and Computer Engineering Dept.ĭirectory named for the release version. The tools are currently maintained by operators in the CADE Lab,Īnd Erik Brunvand in the School of Computing, and to a lesser extent To speed programming in the tcl language: The following web page is a good reference for getting up Many tools are now being converted to using the tcl scripting The documentation scripts normally start with a Versioning is beginning to be implemented here as well, through theĭirectory F06 to get the old programs and scripts.ĭocumentation scripts for the tools are in the same directory as the The setup scripts called by these wrappers are in You currently need to have the S06 version in your path to get all the Place the S06 version first, you will mostly get all the old tools. Order in which these are in your search path is significant. Number, while still allowing us to upgrade the tools. This allows users to develop under a particular release or version uusoc/facility/cad_common/local/bin/ under the followingĭirectories based on the tool release, unless otherwise described: Script as a starting point for your own customizations. Need something different, you should probably start with the setup We know that they work with these configurations. That you use these wrappers, or at least these startup scripts, to use Setups in a new shell then call the tool. In addition, there are wrappers that source these Variables, etc.) we've put these startup constraints into setup filesįor each tool group. These tools often have complex environment requirements (paths, They are automounted such that youĪlways get the right binaries for the machine type you're on. VLSI and digital/analog circuit CAD tools in the College ofĮngineering are available on CADE and CS machines. 3.ģ.7 The output file of PrimeTime is Standard Delay Format (.sdf) and it includes delay information, such as pin-to-pin cell delays and net delays, and timing checks, such as setup, hold, recovery, and removal times.VLSI/Circuit CAD Tools in the College of Engineering The report can also be seen in the Timing Analysis Driver Console by remarking one of the rows and clicking the inspector button. Startpoint: out_reg (rising edge-triggered flip-flop clocked by clk)Įndpoint: out (output port clocked by clk)Ĭlock network delay (propagated) 3.7571 3.7571 Start PrimeTime graphical user interface (GUI) from the work directory, which is located in the post_lay directory. ![]() The steps to run PrimeTime with the results from Design Compiler are very similar.ġ. This lab is based on using results from IC Compiler. If PrimeTime is given results from Design Compiler then work in the pre_lay directory, and if PrimeTime is given results from IC Compiler then work in the post_lay directory. PrimeTime is a full-chip, gate-level static timing analysis tool that is an essential part of the design and analysis flow for today's large chip designs. Learn how to use PrimeTime to validate the timing performance of a design by checking all possible paths for timing violations, without using logic simulation or test vectors. ![]() Static Timing Analysis of Test Patterns with PrimeTime Objective
