Limitations of STA Timing Design STA by VLSI Universe - July 11, 2021July 20, 20210 Static timing analysis helps to find timing issues in almost all aspects of a design and is very important to have a VLSI chip with no timing problems. But there are still some cases where STA timing verification cannot be completely applied and verified. Let us discuss some of such difficulties or limitations of STA in the below article. You can read these STA (Setup time and Hold time) and STA-related problems with solutions articles to understand static timing analysis first. Calculating maximum operating frequency and checking for setup and hold time violations are described in detail. STA during Reset Sequence When there is an asynchronous or synchronous reset, we need to check whether all the flip-flops got reset. The flops must reset into
SOC Design Life Cycle VLSI Chip 2021 VLSI Design by VLSI Universe - July 11, 2021July 21, 20210 Basics of System on chip (SOC) design (IP based or Platform based) with the need of SOC, SOC architecture, Advantages of SOC, and various examples of SoCs available in the market are discussed here. A System on Chip (SOC) is nothing but an integrated circuit (IC) with a full-proof system or a complete computer on a single platform chip. The SOC design may be followed as an IP-based design or a platform-based design. SOC definition and its Need System on chip (SOC), is an integrated circuit where all the functional elements such as dedicated hardware, processor, memory, I/O, and peripherals are embedded onto a single platform chip to meet the product design requirements. Need for SOC design 1. With the advancement in the technology, it
VLSI systems second sem study material VLSI Design by VLSI Universe - July 2, 2021July 20, 20210 The study material for VLSI System second semester is listed here. Important subjects like VLSI Testing and Design of ASICS will be covered this semester. This semester becomes very crucial for the student as he has to prepare for interviews also and a regular curriculum also. Also if the candidate has got less CGPA in the first semester then he has to cover up here. Along with the second-semester candidate also have to revise first semester subjects like analog, digital, Verilog, and basics of VLSI. Compared to the second semester the first semester will be a bit short in time and the first semester gets over as soon as the student gets set well with the academics. In this article, I will

CAM cell in memory and its application 2021 OS concepts by VLSI Universe - June 14, 2021July 21, 20210 A content-addressable memory CAM (similar to SRAM) is an associative storage memory that addresses(searches) the content present in the computer. It compares the provided input data with the table of values and returns the address of matched data location. Basics of Content Addressable Memory(CAM) Content-addressed memory or CAM is like the combination of an SRAM with some added searching functionality to it. It does work like an SRAM such as it can read data from the particular memory location and it can write data on the intended memory location. Its main operation other than acting like an SRAM is performing a matching or searching operation. A valid search asserts the output match-line in other words an input value being found in the particular
