Verilog-AMS 2023 Standard Available for Download

Accellera recently released the Verilog-AMS 2023 standard for download.  The updated standard introduces enhancements to analog constructs, along with clarifications for existing constructs.

Updates to the Verilog-AMS 2023 standard include:

  • Dynamic tolerance to event control statements
  • Jump statements for analog constructs
  • Numerous clarifications such as interrupted transitions, context, and named events
  • Additional $receiver_count() function for connect modules
  • Compiler directives for UVM-MS

Verilog-AMS benefits users by allowing them to describe and simulate analog and mixed-signal designs using a top-level design methodology as well as the traditional bottom-up approaches. The standard supports analog and mixed-signal designs at three levels: mixed transistor/gate-RTL/behavioral circuit, transistor/gate-RTL/behavioral, and transistor/gate. Moreover, Verilog-AMS provides powerful structural and behavioral modeling capabilities for systems in which the effects of, and interactions among, different disciplines such as electrical, mechanical, and thermal are important.
