Understanding Shmoo Plots and Various Terminology of Testers
WEB3. Wall Shmoo. Wall Shmoo depicts a failure at a certain voltage irrespective of any variation in frequency. This kind of Shmoo leads to indicate the problem of noise coupling, race condition, and charge sharing. The noise can be aggravated by higher di/dt (higher inductance) and dv/dt (higher capacitive coupling).
Design Rule Checks (DRC) - A Practical View for 28nm Technology
WEBThis whole process is called Design Rule Checking (DRC). There are many design rules at different technology nodes, a few of which are mentioned below. Types of DRCs: Minimum width and spacing for metal. Minimum width and spacing for via. Fat wire Via keep out Enclosure. End of Line spacing. Minimum area.

Usage of Multibit Flip-Flop and its Challenges in ASIC Physical …
WEBMultibit flops are used to reduce the power in ASIC without affecting the performance of the design. Multibit flops as the name suggests have multiple D and Q pins. Generally, two bit and four bit versions are available in the library. A two bit multibit flops will have D0, D1, Q0, Q1 pins along with a common clock, scan_in and scan_enable pins ...

Understanding Logic Equivalence Check (LEC) Flow and Its …
WEBLogic Equivalence Check, popularly known as LEC is one of the most important parts of the ASIC VLSI design. Formal verification techniques have been developed using mathematical proof rather than simulation or test vectors to provide a higher level of verification confidence on properties. For example, the implementation can be either a Verilog ...
PCIe error logging and handling on a typical SoC - Design And …
WEBIn Today’s high speed systems PCI Express (PCIe-Peripheral Component Interconnect-express) has become the backbone. PCIe is a third generation high performance I/O bus used to interconnect peripheral devices in applications such as computing and communication platforms. It is used to provide the ...
UVM RAL Model: Usage and Application - Design And Reuse
WEBUVM RAL is an object-oriented model for registers inside the design. To access these design registers, UVM RAL provides ready-made base classes and APIs. Some of the RAL model features are: Just like design, it supports different register attributes like R/W, RO, WO, W1C, etc. Supports two different paths for register access, frontdoor and ...
Demystifying MIPI C-PHY / DPHY Subsystem - Design And Reuse
WEBFor D-PHY this can be accomplished by using four-lane D-PHY, using 10 wires, each Lane running at 1.0Gbps/lane. To obtain the same aggregate data rate at the same or lower transition rate with C-PHY, we can use two-lanes C-PHY, with 6 wires, running at 0.875Gsps, which is less than the 1.0Gsps for the D-PHY.
