YAML in Semiconductor EDA: From Configuration Language to Reusable Design-Flow Methodology

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.

Modelling of Binary Encoding, Gray Encoding and One-hot encoding FSM using Verilog HDL

Hello Dear Readers,   Today, I will explain how binary, gray, one-hot encoding FSM design using Verilog HDL. 1). Binary Encoding: Binary encoding style can be used if the area requirement is a constraint on the design. In this encoding style state parameters for the binary encoding are represented in the binary format. Two-Bit Binary Up-Counter FSM: Two-bit binary counter FSM is described below, the number of states is equal to 4 and it needs four state variables ‘s0,’ ‘s1,’ ‘s2,’ and ‘s3.’ The number of flip-flops used to represent the functionality of the counter is equal to 2. The state transition table and the state transition diagram is shown in Fig.1 and Fig.2. The transition from one state to another state occurs on the positive edge of the clock. The default state is ‘s0’ and it is the reset state. So outcome is Moore machine as the output is a function of the current state only.
