Change list, formatted as text:
 1. insert_buffer in <top>: added one 'dl01' 'A' to 'Y' on pin 'xxx_reg/Q' named 'net_PTECO_HOLD_NET1' 'U_PTECO_HOLD_BUF1'
 2. insert_buffer in u_submodule1: added one 'buf01' 'A' to 'Y' on pin 'xxx_reg_2_/D' named 'net_PTECO_HOLD_NET2' 'U_PTECO_HOLD_BUF2'
 3. size_cell in u_submodule2: 'U296' sized to 'buf01'
 4. size_cell in <top>: 'U001' sized to 'nand02'
