Frequently Asked Questions


All systems with x86 architecture or above with linux OS (recommended ubuntu 16.04, RedHat 7 or above) installed can run atssim. We recommend at least 4 GB RAM for individual license run to simulate module level designs. If users are running system level testcases using UVM methodology, then large RAM (16 BG or more) is required based on complexity of design.

The best setup for industries is to use a high speed server having a RAM of 16 GB or higher in a linux environment.

We do not recommend more than 5 licenses (means 5 users) on any server, because when system level designs are simulated with UVM based verification environment then it consumes big amount of RAM and thus slowing down performance of system considerably.

atssim simulator is configured to access license server once in a 24 hours span for verifying license validity. Therefore, internet access is required at least once in 24 hours.

Yes, a trial version license of 30 days is available for free of cost. In trial version advance features of SV are disabled. Please see download menu to know more about trial version of atssim.

Currently, beta release of atssim is available for beta testing partners.

We have successfully tested atssim for more than 2000 unit/ module level testcases and more than 40 UVM based testcases.

Product update will be placed on site once in a week every Friday EOD. Occasionally we can place updated package on Wednesday too.

Please refer support menu for details on installation.

This product consists of a compiler and event based simulator.

User can generate VCD or dump file and use any common waveform viewer to view/ analyze waveform. We recommend gtkwave VCD file viewer, which is available as inbuilt add-on package with ubuntu or other linux platforms.

We have plans to provide waveform viewer extension as soon as possible.

Yes, It supports functional coverage and concurrent assertions to make verification more measurable and accurate.

Yes, you can write verification components in C++ and integrate them with your SV/ UVM based testbench using DPI (Direct Programming Interface). atssim supports DPI.

Yes, It supports UVM.
