How FPGA is Programmable ASIC and Its Building Blocks

  Hello Dear Readers,   Today in this post I will discuss how FPGA is a programmable ASIC and what are the basic building blocks of the FPGA. Modern FPGAs are named programmable ASICs and used in various applications which include the ASIC SOC designs and prototyping. FPGA programming includes the following types and is discussed below section. The main programming types for any FPGA are, 1). SRAM Based FPGAs: Most of the FPGAs in the market are based on SRAM technology. They store the configuration bit-file in the SRAM cells designed using latches. As the SRAM is volatile, they need to be configured at the start. There are two modes for programming and they are Master and Slave. The SRAM memory cell is shown in Fig.1. In the Master mode, FPGA reads configuration data from the external source and that can be flash. In the Slave mode, FPGA is configured by using the external master device such as processor. The external configuration interface can be JTAG that is also call...

Architecting Speed in FPGA

  Hello Dear Readers,   Today in this post we will discuss how the architecting speed inside will be changing by writing efficient RTL coding. Sophisticated tool optimizations are often not good enough to meet most design constraints if an arbitrary coding style is used. Here we will discuss the first of three primary physical characteristics of a digital design speed and also discuss methods for architectural optimization in an FPGA. There are three primary definitions of speed depending on the context of the problem: throughput, latency, and timing. In the context of processing data in an FPGA, throughput refers to the amount of data that is processed per clock cycle. A common metric for throughput in bits per second. Latency refers to the time between data input and processed data output. The typical metric for latency will be time or clock cycles. Timing refers to the logic delays between sequential elements. When we say a design does not “meet timing,” we mean that the de...

STANDARD CELL LIBRARY LAYOUT DESIGN - PART-2

  Hello Dear Readers,   Today in this second post we will discuss further standard cells. A standard cell consists of a set of transistors and their connections which implements a boolean logic or a storage function. Although it is possible to generate any boolean function using only a NAND (or a NOR) gate, the designs will be more area effective by including other logical gates in the library. The elementary gates such as Buffer, Inverter, NAND, NOR, XOR, and memory cells are often found in any standard library while the rich and fancy libraries contain additional gates with higher complexity such as adders and multipliers. The initial design of a standard cell begins with implementing the functionality of the Cell at the transistor level. The schematic view of a cell is used for this purpose. In addition, schematic views are widely used for simulating and debugging circuits. The schematic of a cell can be represented by symbol view which consists of the input and output port...

STANDARD CELL LIBRARY LAYOUT DESIGN - PART-1

   Hello Dear Readers,   Today in this entire series I will give you an idea about how the standard cells library which included layout design of the basics all the gates and circuits is formed. The growing demand for the integration of systems with the maximum possible functionality by combining high performance with a tolerable amount of power dissipation has been driving the development and the modeling of CMOS transistor technologies, especially with the growth of the embedded and portable devices market. The need for integration of more and more components onto a single chip, by improving performance with reasonable energy loss, motivated the migration to the deep sub-micron regime. The key success factor for the rapid growth of the integrated system is the use of ASIC library for various system functions. It consists of pre-designed and pre-verified logic blocks that help designers to shorten product development time and manage the complexity of a chip having millio...
