Decap cells are basically a charge storing device made of the capacitors and used to support the instant current requirement in the power delivery network. There are various reasons for the instant large current requirement in the circuit and if there are no adequate measures have taken to handle this requirement, power droop or ground … Read more
Well tap cells (or Tap cells) are used to prevent the latch-up issue in the CMOS design. Well tap cells connect the nwell to VDD and p-substrate to VSS in order to prevent the latch-up issue. There is no logical function in well tap cell rather than proving a taping to nwell and p-substrate therefore … Read more
Standard cell library is an integral part of ASIC design flow and it helps to reduce the design time drastically. Standard cells used in the ASIC design is a part of a standard cell library along with some other file sets. In this article, we will discuss the important content inside the standard cell library … Read more
Standard cells are well defined and pre-characterized cells used in ASIC (Application Specific Integrated Circuit) Design flow as basic building blocks. All these cells are equal in height and can easily fit into the standard cell row. Standards cells are highly reusable and save lots of ASIC design time. Standard Cell Layout All the Standard … Read more
