Mike, You gave me an AR to check the quotes around VHDL-AMS related text in the draft. Here is what I found: The digital signals in VHDL-AMS are std_logic and their values are enclosed by a single quote (tick) mark, for example '1'. So on pg. 93, the 2nd paragraph should have these single quotes instead of double quotes, like this (in red bold): The digital ports delivering signals to the AMS model, D_drive, D_enable, and D_switch, must be limited to the '1' or '0' states for VHDL-AMS, or, equivalently, to the 1 or 0 states for Verilog- AMS. The D_receive digital port may only have the '1', '0', or 'X' states in VHDL-AMS, or, equivalently, the 1, 0, or X states in Verilog-AMS. All digital ports other than the foregoing predefined ports may use any of the logic states allowed by IEEE Std. 1164-1993, or later. Similarly, on pg. 97-98 and 113-114 there are a few references to digital states, which should all be single quoted for VHDL-AMS. The easiest way to find these is by searching for "0", "1" and "X". You will find one more reference to digital states on pg. 171 in the AMI section: as to whether the data bit is a "1" or a "0"). I don't think this needs to be changed to single quotes, because this is not a reference to the VHDL-AMS std_logic value. That's all I could find on this topic...

Please find enclosed version 0.130 of the IBIS 5.1 draft (these copies, along with a Microsoft Word version, have been posted to the website). Note the following changes: - Bob Ross's new Section 10 structure has been implemented - Improved formatting on all figures - Corrections to keyword/required formatting - Single and double quote consistency - Grammatical fixes - Additional text in Section 1 on 5.1 features - Updated UI description text - Consistent use of format on "Example/Examples" - "Shall" for "must" in Section 6C and Section 10 Please check over Sections 6C and 10, particularly on the placement of Gaussian and related terms (new text is still needed there). Additionally, parts of Section 10 may still need reordering to make String, Float, Integer, etc. more global. - MM
