This article mainly shows you "Linux system how to install Cadence", the content is easy to understand, clear, hope to help you solve your doubts, the following let the editor lead you to study and learn "Linux system how to install Cadence" this article.

Introduction to Cadence: Cadence is a large-scale EDA software that can complete almost all aspects of electronic design, including ASIC design, FPGA design and PCB board design.

Cadence has absolute advantages in simulation, circuit diagram design, automatic layout and routing, layout design and verification.

Most of the tools included in Cadence cover almost every aspect of EDA design.

one。 Preparation work 1. Download, link: https://pan.baidu.com/s/1O89UtzCT5jDgXhcvacXJYQ password: etg3 (this installation package is for learning only, if the link fails, please contact the blogger to update) 2. Extract the IC617 package in the following figure. Note that this compression package is volume-by-volume compression. You need to unpack one of them in the same folder. The directory is optional. The 7z command is required for decompression. 3. Set up the installation directory, install it in the / eda/cadence directory (or / opt/cadence, etc.), and create the IC617 and installscape directories in the cadence directory. 4. What will be downloaded

Move to the / opt/cadence/installscape directory and extract it.

two。 Start installation 1. Start the installation package

Sh / eda/cadence/installscape/iscape/bin/iscape.sh2 if the operating system environment is configured correctly, it will enter the following graphical installation interface Note: an error such as lack of java or other libraries occurs at this time, indicating that the environment needs to be configured.

two。 Set up the installation directory, go to Preferences = > InstallScape = > Directories, and select the installation directory you created

3. Install IC617, enter Local directory/Media install, find the IC617 unzipped directory (the unzipped directory of the five packages), select IC_06.17.702 and continue, select the default installation directory, and finally start wait for the installation to be completed.

Note: if you re-select the RHEL 4. 0 release disk1 path at this time, there is an error in the IC617 installation package: 1. Decompression error, which is caused by the failure of decompression of a single file during the decompression process. two。 The file is not fully unzipped. There is a .zip file in the kit folder. Try to extract it before continuing. 3. Installation package error, look for other installation packages.

4. After the installation is completed, you will automatically enter configure, choose whether to install AMS Designer or not, select 2 Quit read seconds, and then select "y" to confirm the installation of libraries, "n" does not change the OA installation directory / opt/cadence/IC617/oa_v22.50.036 (this installation path is not recommended to change, you need to set the environment variable OA_HOME, setting this environment variable will lead to some unnecessary version conflicts).

5. At this point, if Success appears in both install status and configure status, it is complete. If configure displays failed, select configure releases in the menu list to reconfigure.

three。 Environment configuration 1. Patch IC617 move the downloaded patch folder to the installation directory / eda/cadence,cd to that directory, execute the command:

. / cadence_patch.sh / eda/cadence/IC617 12. Generate license.dat cd to the folder where you downloaded the cadence_license and execute the command:. / licgen.sh to generate license.dat. License can also be generated under the window system. (there is an error in this step. Refer to the REDME in the folder for details. You can also generate license under window). Delete the first four lines of license.dat, leaving only the paragraphs that begin with FEATUE. Move the generated license.dat into / eda/cadence/IC617/share/license.

3. Changing the environment variable can set the Cadence environment variable directly, but it is likely to have an unpredictable impact on the normal operation of the system. Therefore, it is best not to change it directly. It is recommended to use the following method: the download package contains the existing bashrc, change its variable address, and bashrc contains a series of tools such as cadence. Here we only install IC617, so we only need to change these two lines:

Export CADHOME=/eda/cadence export CDS_LIC_FILE=$CADHOME/IC617/share/license/license.dat12 and add virtuoso on the last line. After saving, it is recommended to rename it to .virtuoso, change permissions 755, and put it in $HOME, so that you can run the file on the current terminal, automatically configure environment variables and run virtuoso, so that the environment variables of the entire system are not affected.

4. Start command

. .virtuoso & 1
