Si2 Corporate Membership (Base) is available to any company who uses, designs, or supports EDA Software Tools.


The prospective member must review the Si2 Antitrust Guidelines and Si2 Bylaws (below) before completing the membership agreement. Membership dues is based on company revenue. Please obtain a quote prior to emailing or faxing in your agreement.

In 2015, the Si2 Base Membership became an integral part of each Coalition membership, so no additional base dues is required for Coalition members.

For companies joining after mid-year, dues can be prorated from June 1, however, a full year’s dues payment is required. The following year dues will be invoiced for just six months, bringing renewal in line with the calendar year.
