This is a test chip which contains a bunch of digital logic cells that have been automatically layouted with Libresilicon's StdCellLib and have been directly connected to the IOs, so that you can use their logic functions directly: INV, AOAAOI2124, MUX8, AAOAOI33111, AAAOAI3221, ASYNC3, AAOI22, AAAOI222, NAND4, AAAAOI3322, AAAOAOI33311, AAAOI333
