To change block sizes within a design, Buffer Up creates a new layout within Audio Weaver and is used in conjunction with Buffer Down. This layout will appear as a continuation of the signal flow in the same design file, however the portion of the system between Buffer Up and Buffer Down will operate at a different block size (whole number multiple of the input block size) and in a different layout, designated in the module’s properties tab.
The thread, (or layoutSubID) allows you to run multiple sets of modules at the same clockDivider in different layouts by setting the block size, and layoutSubID. For instance, the system input pin is always in layout 1A, and any layouts with the same clock divider could reside in 1B, 1C, alphabetically up to 1P. By changing to a higher block size, the user would be creating a second clock divider, where the user can add up to 16 layout subIDs in this new block size (2A, 2B, 2C, etc.).
