Hi,
I found this link in the forum with a problem that i solved: https://www.edaboard.com/showthread.php?t=319722
However, i cannot answer anymore, so I created this new thread.
The Nangateopencelllibrary 45 nm SDFF has a problem in the .lib file.
The .lib does not present a "test_cell" function. Its necessary include something like the following lines in the SDFF .lib to allow the tool to recognize de SDFF and replace the standard flops:

clear : "(!RN)";
preset : "(!SN)";
clear_preset_var1 : H;
