Hello Dear Readers, Today in this post, I will provide some deep insight about yaml langauge for CAD flow developments with detailed examples. YAML is not a programming language in the same sense as Python, Tcl, C++, or Verilog. It is primarily a human-readable data serialization/configuration language . In semiconductor EDA, that distinction is important because YAML generally describes what a flow should do , while Python/Tcl/Shell and the EDA tools execute the flow . The official YAML specification describes it as a data serialization language designed to be human-friendly and portable across programming languages. For the semiconductor angle, this becomes particularly interesting because YAML can act as a configuration layer between design methodology and EDA implementation . Frameworks such as Hammer explicitly use YAML/JSON configuration and an intermediate representation to standardize information exchanged between design, technology, and tool plugins. 1.

Hello Dear Readers, Today in this post I will provide some deep insight into Computer-Aided Design (CAD) Tools. So let's start. Computer-aided design (CAD) tools have advanced significantly during the past decade, and nowadays digital design is performed using a variety of software tools. Prototypes or even final plans can be created without discrete components and interconnection wires. Fig. 1 illustrates the steps in modern digital system design. Like any engineering design, the first step in the design flow is formulating the problem, stating the design requirements , and arriving at the design specification . The next step is to develop the design at a conceptual level, either at a block diagram level or at an algorithmic level. Fig. 1: Design Flow in Modern Digital System Design Design entry is the next step in the design flow. Previously, this would have been a hand-drawn schematic or blueprint. Now with CAD tools, the design conceptualized in th...
