Integrated circuit layout software developer Silvar-Lisco Inc has introduced a vendor-independent layout systems for the design of large gate arrays and dubbed it Avant Gards – Advanced Gate Array Design System. Silvar-Lisco claims that the software can design arrays of over 150,000 used gates, at densities never before achievable and it can use sea-of-gates and thrre-layer design styles. By vendor- and technology-independent Silvar Lisco means that buyers are no longer captive to a single foundry. It is fully integrated with Silvar’s integrated circuit layout computer-aided engineering software products and can be customised to for special technology or foundry requirements. Avant Gards will operate on DEC, Sun and Apollo equipment and is integrated with Silvar-Lisco’s other chip design software which include design capture, logic design verification, design layout and physical design verification. Avant Gards will be out in 60 days.
