Cadence Tempus

The Cadence® Tempus™ Timing Signoff Solution is the static timing analysis (STA) tool for FinFET designs. The Tempus solution is designed to tackle the most advanced timing requirements including full signal integrity (SI) analysis, glitch analysis and propagation, statistical on-chip variation (SOCV), multi-mode and multi-corner (MMMC) analysis, static and dynamic power reduction, and hierarchical timing models.

Prerequisites

Cluster is built with the desired configuration for networking, storage, compute etc. The simple_hpc_pbs template in the examples directory is a suitable choice.

After cluster is built, first copy the apps directory to the cluster. The azhpc-scp can be used to do this:

azhpc-scp -u hpcuser -r $azhpc_dir/apps hpcuser@headnode:.

Then connect to the headnode:

azhpc-connect -u hpcuser headnode

Installation

Change folder to:

cd /azurehpc/apps/cadence_tempus

Take a look at the 'build_tempus.sh' script, modify the installation directory if needed:

vim build_tempus.sh

Run the 'build_tempus.sh' script:

source build_tempus.sh

Configure License Server

Make necessary modification of the license file you received from Cadence or supplier. EX: modify the SERVER name:

...
########################### LICENSE KEYS START HERE ######################
SERVER Cadence_SERVER 000d3a5f9947 5280
DAEMON cdslmd ./cdslmd
# DO NOT REMOVE THE USE_SERVER LINE
USE_SERVER
...

Copy the license file to the VM (EX: headnode), and then execute:

[your installation directory]/bin/lmgrd -c License_46499_000d3a5f9947_7_2_2020.txt -l license.log

Run Tempus

You are able to run your Tempus simulation on the cluster. See smote_test.sh for example. Below a sample result from monitor_host.log:

Status keys: E excellent, G good, B bad, T terrible.
Memory values:
  total = Real memory of host
  progs = Real memory used by processes, including swappable cache
  used =  Real memory used by processes, excluding swappable cache
