Limitations of Dielectric Bricks
Diagonal fill is not allowed for dielectric bricks. All dielectric bricks must use “staircase fill”. Thus, dielectric bricks with curved or rounded edges must be stair step approximated. Note that the error caused by such an approximation decreases as the X and Y cell sizes are decreased. Thus, it is possible to make this error arbitrarily small by choosing sufficiently small X and Y cell sizes.
The Keysight ADS Interface, Cadence Virtuoso Interface and Cadence AWR MWOffice Interface do not create dielectric bricks.
