<strong>Top</strong>-<strong>down</strong> <strong>digital</strong> <strong>design</strong> <strong>flow</strong> / Chapter 1: Introduction 41.3 EDA tools and <strong>design</strong> kit configurationIn order to use the EDA tools and the <strong>design</strong> kit, a file called edadk.conf must exist either in your homedirectory or in the directory from which the tools are launched (the top‐level project directory. This filemay exist in both directories, the content of the edadk.conf file in the working directory superseding thedefinitions in the same file in the home directory.The edadk.conf file must include the following lines (order is not important):mgc msim 6.2csnps syn 2005.09cds soce 4.1cds ic 5.1.41dk ams hk370This file is recognized on the immsunsrv1 and immsunsrv2 Linux machines only.1.4 Installation of the AMS <strong>design</strong> kitTo install the files required by the AMS <strong>design</strong> kit, execute the ams_setup script in the top‐level project directoryas follows:where:ams_setup -p -t -p select process-t select toolsetRunning the command without arguments displays a short help.To install the 0.35 micron CMOS called C35B4 for logic simulation and synthesis, use:[28]vachoux@lsmsun1-ADDSUB> ams_setup -p c35b4 -t synopsys_dcThe command produces the following output 1 :IMPORTANT NOTICEAll AMS documentation and <strong>design</strong> files made available with this commandare subject to non-disclosure agreements between Europractice, AMSand EPFL, and hence must be considered as strictly confidential.For more information: Alain Vachoux, STI-LSM, alain.vachoux@epfl.ch.-- Configuration parameters:AMS HIT-Kit version v3.70Process: c35b4Tool : synopsys_dc-- Configuration log:File "./.synopsys_dc.setup" createdFile "./modelsim.ini" createdLink "LIB/C35_CORELIB_VLOG" to ".../c35_corelib_vlog" createdLink "LIB/C35_IOLIB_3M_VLOG" to ".../c35_iolib_3m_vlog" createdLink "LIB/C35_IOLIB_4M_VLOG" to ".../c35_iolib_4m_vlog" createdDirectory "./LIB/SNPS" createdDirectory "./LIB/MSIM" createdModelsim library WORK mapped to ./LIB/MSIMSynopsys library WORK mapped to ./LIB/SNPSThe command creates configuration files for Modelsim and Synopsys as well as the required <strong>design</strong> librariesfor hosting compiled VHDL/Verilog models and for simulation.1. The output is slightly different if the project directory structure has not been created first.AVx / Version 3.1 - November 2006
