- Linear ASICs¶
- Mentor¶
- Mentor Graphics¶
Mentor, a Siemens Business is a US-based electronic design automation (EDA) multinational corporation for electrical engineering and electronics.
- OSU¶
Oklahoma State University
- VSD¶
- VLSI System Design¶
- sc¶
- Standard Cell¶
The basic building blocks of digital circuit design.
- ce¶
Memory Core
- Antenna Rule Violations¶
During manufacturing, a static charge can build up on the currently- topmost metal layer, and destroy the chip if there is no path to the substrate for this charge to bleed off during layer deposition. The Antenna Rule ensures that each metal layer has a route to diffusion.
- CIF¶
- Caltech Intermediate Form¶
From the 1990’s, the CIF format has largely been replaced by the GDS format.
- CCS¶
- ECSM¶
Current Source Models
- DRC¶
- 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.
- ESD¶
- Electro-Static Discharge (protection from)¶
Circuit elements, especially on I/O pins, intended to protect the circuit from the effects of electrostatic discharge.
- LVS¶
- Layout Verse Schematic¶
Layout Versus Schematic (LVS) verification is the process of determining whether a particular integrated circuit layout corresponds to the original schematic or circuit diagram of the design.
- 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).
- MoM¶
- MoM caps¶
- 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.
- NLDM¶
Non-Linear Delay Model
- OPHW¶
- OPen HardWare¶
The movement to produce inspectable and modifiable computer hardware designs.
- PEX¶
- 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.
- PNR¶
- Place aNd Route¶
The process of laying out the standard design cells on the 2D plane of the chip and connecting their corresponding inputs and outputs. Theoretically equivalent to the “Travelling Salesman Problem,” and therefore the subject of much research.
- STA¶
- Static Timing Analysis¶
Analysing the timing of a circuit from some level of the design. Contrast with performing the timing analysis on actual hardware.
- RTL¶
- Register Transfer Language¶
A source code format that describes the transitions that hardware registers take at the register transfer level, such as Verilog or VHDL.
- VLSI¶
- Very Large Scale Integration¶
Producing an integrated circuit in the million+ transistor scale, with multiple functions on the same chip (such as compute, memory, ROM, and power regulation).
