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. Introduction M...

SDC (Synopsys Design Constraints) contents part 4

Today, we will be discussing the remaining constraints mentioned in the SDC, which pertain to timing exceptions and design rules. This is the final part of the SDC contents. This is going to be interesting, especially with multicycle paths. Take time to read and try to comprehend. 10. set_max_transition     By setting max transition value, our design checks that all ports and pins are meeting the specified limits mentioned in SDC. If these are not satisfied then timing report will give DRVs (design rule violations) in terms of slack. This is specified as               set_max_transition 0.5  UBUF1/A setting maximum limit of 500ps on pin A of Buffer1. 11. set_max_capacitance     This is same as max transition, setting the maximum capacitance value. if our design not meeting this value then violation will occur. This will also reports under design rule violations in terms of slack.     set_max_capacitance 0.7 [all_...

SDC(Synopsys Design Constraints) contents part 3

  Dear readers, today we will be discussing the IO-related constraints mentioned in the SDC file. The reason for defining the commands in the SDC file and their significance. STA cannot check the paths which are not constrained. Therefore, all paths must be constrained. 5. set_input_delay      This tells us how much time data will be delayed with respect to the clock to reach the input port of our design. That is the delay used by the external logic. So, the designer can estimate how much time is left for internal logic to meet the targets. For example, The delay at the input port defined by the combined delay of clock to Q delay of UFF0 and combinational delay. This delay is defined with respect to the CLKA. This is specified as          set_input_delay 1.5 -clock CLKA  [get_ports INP] Input delay can be specified for worst case slow (max) corner and best case fast (min) corner.              ...
