FPGA virtex fpga bitcoin miner be used in many different applications. For smaller designs or lower production volumes, FPGAs may be more cost effective than an ASIC design, even in production. ASIC can run into the millions of dollars. The initial ASICs used gate array technology.

8-bit ZX81 and ZX Spectrum low-end personal computers, introduced in 1981 and 1982. O solution aimed at handling the computer’s graphics. Customization occurred by varying the metal interconnect mask. Gate arrays had complexities of up to a few thousand gates. Some base dies include RAM elements.

In the mid-1980s, a designer would choose an ASIC manufacturer and implement their design using the design tools available from the manufacturer. While third-party design tools were available, there was not an effective link from the third-party design tools to the layout and actual semiconductor process performance characteristics of the various ASIC manufacturers. Most designers ended up using factory-specific tools to complete the implementation of their designs. Standard-cell design is the utilization of these functional blocks to achieve very high gate density and good electrical performance. Standard-cell design fits between Gate Array and Full Custom design in terms of both its non-recurring engineering and recurring component cost.

This process is analogous to writing a computer program in a high-level language. Each technique has advantages and disadvantages, and often several methods are used. RTL design into a large collection of lower-level constructs called standard cells. 2 input nor, 2 input nand, inverters, etc. The standard cells are typically specific to the planned manufacturer of the ASIC. It attempts to find a placement of the standard cells, subject to a variety of specified constraints.
