IEC 61691-6:2021（E）定义了IEC 61691-6/IEEE Std 1076.1语言，这是一种硬件描述语言，用于描述和模拟、数字和混合信号系统。该语言也称为VHDL-AMS，建立在IEC 61691-1-1/IEEE 1076（VHDL）语言的基础上，并对其进行扩展，以提供编写和模拟模拟和混合信号模型的能力。本标准以双标识IEC-IEEE标准发布。

IEC 61691-6:2021(E) defines IEC 61691-6/IEEE Std 1076.1 language, a hardware description language for the description and the simulation of analog, digital, and mixed-signal systems. The language, also informally known as VHDL-AMS, is built on the IEC 61691-1-1/IEEE 1076 (VHDL) language and extends it to provide capabilities of writing and simulating analog and mixed-signal models. This standard is published as a double logo IEC-IEEE standard.
