System Verilog Macro: A Powerful Feature for Design Verification Projects SV macro is one of the most powerful features out there and if used properly with a thorough understanding and applied wisely in a DV project, it can help to save a lot of time and can make the code more readable and efficient. This paper shows how, using SV macro with the proper syntaxes, a DV engineer can break up the larger complex code in smaller chunk and can reuse it at many places. |

Dynamic Memory Allocation and Fragmentation in C and C++ In C and C++, it can be very convenient to allocate and de-allocate blocks of memory as and when needed. This is certainly standard practice in both languages and almost unavoidable in C++. However, the handling of such dynamic memory can be problematic and inefficient. For desktop applications, where memory is freely available, these difficulties can be ignored. For embedded - generally real time - applications, ignoring the issues is not an option. |

Layout versus Schematic (LVS) Debug In ASIC physical implementation, once layout is generated, it must follow all the design rules for successful manufacturing and must match the schematic of the required design. To ensure this in physical verification, Design Rule Check (DRC) is carried out to check whether the layout follows the rules for fault-less manufacturing or not. |

Synthesis Methodology & Netlist Qualification The main objective of this article is to explain synthesis flow and post-synthesis netlist quality checks. In ASIC flow, synthesis is the part of the front-end design, while the back-end design takes the synthesized netlist as an input. So, the synthesized netlist should meet all netlist quality checks to reduce multiple iterations, which reduces the turnaround time and efforts. |

Demystifying MIPI C-PHY / DPHY Subsystem The newest member of the MIPI® PHY family, the C-PHY, arrived in October 2014 to a mixture of excitement and apprehension. How would this new C-PHY compare to the MIPI D-PHY and M-PHY®? What would differentiate the C-PHY, and would it be compatible enough with the D-PHY so that both could coexist in a hybrid subsystem? Now, years later, the answers are clear. |

Method for Booting ARM Based Multi-Core SoCs In the boot process various modules/peripherals (like clock controller or security handing module and other master/slaves) initialized as per the SoC architecture and customer applications. In Multi core SoCs, first primary core (also called booting core) start up in boot process and then secondary cores are enabled by software. |

UVM RAL Model: Usage and Application To cope with the speed of the competitive market landscape, most of the systems are designed in a generic way - which means the same design can be used in different ways with different configurations. More the number of configurations, more the number of registers in the design. |
