Siemens certifies Aprisa for TSMC 6nm Siemens has certified its Aprisa place-and-route solution for TSMC’s N6 process. The Aprisa tools offer gate-level-to-GDSII hierarchical and block level physical implementation. Siemens acquired the Aprisa tools from Avatar Integrated Systems in August 2020 to extend its portfolio of world-class IC EDA software. To achieve this latest certification, the Aprisa tools passed a suite of criteria to confirm that the Siemens place-and-route software is ready for mutual customers to start their IC designs on the TSMC N6 process. Under the Avatar banner, and now as a part of Siemens EDA, the Aprisa team has previously collaborated with TSMC on multiple technology nodes starting from 40nm down to 7nm.
