Design Rule Check
|
|
Design Rule Checking
|
|
Design rule checking or check(s) is the process of determing whether the
|
|
physical layout of a particular chip layout satisfies a series of
|
|
required parameters called design rules.
|
|
|
|
LVS
|
|
Layout Verse Schematic
|
|
Layout Versus Schematic (LVS) verification is the process of determining
|
|
whether a particular integrated circuit layout corresponds to the
|
|
original :ref:`schematic` or :ref:`circuit diagram` of the design.

Parasitic Extraction
|
|
Parasitic extraction is calculation of the parasitic effects in both the
|
|
designed devices and the required wiring interconnects of an electronic
|
|
circuit. This includes all parasitic components (often called parasitic
|
|
devices) including parasitic;
|
|
|
|
* capacitances,
|
|
* resistances, and
|
|
* inductances.

CIF
|
|
Caltech Intermediate Form
|
|
From the 1990's, the CIF format has largely been replaced by the GDS
|
|
format.

MiM
|
|
MIM
|
|
MiM caps
|
|
Stands for "metal-insulator-metal" and is a type of IC capacitor
|
|
structure.
|
|
|
|
These are capacitors that are made between two metal route layers,
|
|
usually close to the top of the metal stack.
|
|
|
|
Generally they are around 1fF/um^2, a lot better than MoM caps.
|
|
|
|
The capacitance of MiM caps is on the top and bottom of the metal
|
|
(while the capacitance of MoM caps is sidewall cap).

VPP
|
|
VPP capacitor
|
|
Stands for "metal-oxide-metal" and is a type of IC capacitor structure.
|
|
|
|
These are capacitors which are made by interleaving fingers of metal.
|
|
|
|
Sometimes MoM caps are referred to as "VPP" capacitors (stands for
|
|
"vertical parallel plate").
|
|
|
|
The capacitance of MoM caps is capacitance of the metal sidewalls which
|
|
is significantly lower than that provided MiM caps.
