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.

RTL to GDS-II of FIR Filter Using Open Source Tool Q-flow

   Hello Dear Readers,   Today in this post I will discuss further the  FIR Filter Front-End  implementation at the back-end side by performing the RTL to GDS-II tool Q-flow. For the Installation of the tool follow the steps which are mentioned here below, I have tested my FIR filter Verilog code using Q-flow as shown in Fig. 1 successfully. In which I have selected OSU018 which is 180nm Technology Node. After completing all the steps last one is to click on Edit Layout options will go to us in the Magic tool for displaying the final layout of our RTL code as shown in FIg. 2 where we can see also zero DRC error at top of the middle point.
