Abstract:The gate array with Si-gate CMOS technology and one-and-a-half layer routing are widely used in IC design fabrication, because of its advantages in simple technical support and saving of the chip area. However. it usually uses pre-fixed channel width and limited routing tracks for crossing the macro-cell columns. These limitations give automatic design system many troublesome problems. Therefore many existing algorithms for placemen and routing can not be applied. To accommodate the characteristics of onet -and-a-half layer macrocell gate array. MALS uses new placement and global and channel routing algorithms. The MALS also provides many interactive environment, extraction and verification utilities for the designer to improve the layout and confirming the correctness of their mask layout. The MALS has been used to the design of several chips and is proved as an effective design tool.
Keywords:VLSI CAD  layout  macro-cell gate array
