About This Manual The Design Compiler Command-Line Interface Guide provides basic information about the Design Compiler shell (dc_shell), which is the command-line interface to the Synopsys synthesis tools. Introduction The process that Design Compiler does is RTL synthesis. If there are 2 clocks in design my script will create following cost groups: inputs_2_clk1, clk1_to_clk1,clk1_to_outputs, clk1_to_clk2,. Tc l is used by many Synopsys command shells as a scripting tool for automating design processes. This is usually a. It comes in two flavors: dc shell which has a TCL shell-command interface and design vision which is a gui window/menu driven version. TCL and Perl scripts to help analyze structural properties of RTL within Synopsys Design Compiler suite. If TetraMAX will be given the results of IC Compiler then work in the post_lay directory. /VerdiLog/Verdi. Later I learned TCL and wrote a small script for Modelsim users, which makes icons on the Modelsim GUI. This TCL script is opening the chipfinished cell, and executes run_signoff and signoff_opt. synopsys_dc. Synthesis (Design Compiler dc_shell) The synthesis process is controlled by a script file that the Synopsys tool dc_shell reads. The script and Makefile are also available in GitHub. The argument lets you specify the kernel name, and path to the Tcl script to apply to that kernel. Tcl provides the necessary programming constr ucts—variables, loops, procedures, and so. [TapeOut] 1K-Bytes Rate=0. Invoke dc_shell from the command line after updating your script with "dc_shell-t -f synthesis. saif file generated always has a large number of unannotated inputs and resulting power number is way less than what I get without using the. v) On reading the netlist, check whether the top level design is s27. TestBench -s top_sim xsim top_sim -gui I have taken the *. Design Compiler Files and Example Design. Analysis and Elaboration The analysis command checks your HDL design for proper syntax and synthesizable logic, and then trans-lates this design into an intermediate format inside the speci ed WORK directory.

If the reports indicate performance targets are not being met, code edits may be required. Using Perl's automatic garbage collection facility, the Tcl variables will automatically be unset when the perl Collection object is undef'ed or goes out of scope. SDC files are constraint files. You should, at the very least, look up each command in the synthesis scripts. Why? Is there any utility for me to compile or encrypt the code by using tixwish?. Compiling Tcl on UNIX has two steps: configure and make. Read Design and Libraries. CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Tcl is a highly dynamic language that is especially challenging to execute efficiently. File-> Read (read s27_syn. Default Quartus II Tcl commands provide limited support for reporting timing on non-register-to-register paths and do not report every combinational path between endpoints. tcl is created by Modelsim and put 100 to clock and use compile script in that then use it for Design Compiler. ucli script generated by IC Compiler. Select Design Compiler, and then select a release in the list that appears. Start a terminal (the shell prompt). Synopsys Design Constraints. the "11 rules" that make up the Tcl 8. tcl A tcl script for running automatic synthesis. acs_compile_design (dctcl-mode only) Compiles the constrained RTL to a netlist using constraints propagated from the top-level design. This means, converting a gate level logic Verilog file to transistor level Verilog with the help of Technology library provided by the foundry. The default is the standard output. In tcl also, one frequently uses file operations. All the EDA tool flows from Synopsys, Cadence and Mentor Graphics use Tcl as the primary scripting interface for their flows. Design Compiler Synthesis of behavioral to structural Three ways to go: 1. tcl Synthesis script file my_design. To do this 1(a). 1 The screen when you login to the Linuxlab through equeue. It was influenced by, and bears some similarities to, Lisp.

First we read in verilog file, and optionally DDC files. For information on. A method of generating synthesis scripts to synthesize integrated circuit (IC) designs described in a generic netlist into a gate-level description includes the steps of identifying hardware elements in a generic netlist, determining key pins for each of the identified hardware elements, extracting design structure and hierarchy from the generic netlist, generating script to cause a logic. The following circuit 10 nodes excluding (Out node), delay of each node is represented in the brackets. Instead, everyone uses a TCL shell that comes with Synopsys. tcl " ) The tcl script contain the following:. We've lost 2 months of data due to series of mistakes. Scripting languages provide a high-level application programming interface that enables applications to be created and tested quickly [7]. And do you have an idea how to detect if path group empty or not in tcl script? Let me clarify my problem a little: I automatically create cost groups between all clocks in design in script. - Every command is a string; the first word is the name of the command and the rest are arguments to the command. Tools need to accomplish that (Please suggest the best/simple one) How to compile; How to run the compiled output file ; Thanks. Reasons to learn scripting language are: 1. The Quartus® Prime and Quartus II software includes comprehensive scripting support for command-line and tool command language (Tcl) script design flows. The ICC database in annotated with these signoff numbers. -reset Specifies that netlist change lists should be cleared so that.
