IEC 61523-1:2023

IEC 61523-1:2023 focuses on delay and power calculation for integrated circuit design with support for modeling logical behavior and signal integrity.
The standard specifications covered in this document are as follows:
- Description language for timing and power modeling, called the “delay calculation language” (DCL)
- Software procedural interface (PI) for communications between EDA applications and compiled libraries of DCL descriptions
- Standard file exchange format for parasitic information about the chip design: Standard Parasitic Exchange Format (SPEF)
- Informative usage examples
- Informative notes.
This is an IEC/IEEE dual logo standard.
