Although Mentor Graphics is buying the computer-aided engineering business abandoned by Tektronix Inc, other companies have not been slow to see the transaction as an opportunity to leap in with alternative solutions to those proposed by Mentor. One of the first leaping in to fill the gap it sees for Tektronix users and create a bit of extra business for itself is Valid Logic Systems which has announced a special programme enabling Tektronix CAE Systems customers to migrate to comparable products from Valid. The programme, dubbed White Knight, is intended to serve the Tektronix customer base by offering a transition plan for their software, hardware, maintenance and training to the Valid Electronic Design Automation environment. The Valid Logic environment includes the complete range of VAXstations from DEC as well as workstations from Sun Microsystems. Valid Logic is targetting this programme primarily at customers using Tektronix CAE’s DEC VAX-based electronic design tools, although this offer is open to customers using Apollo-based systems as well.
