About Technology Map Viewer

It would be helpful if you could teach us the following points about Technology Map Viewer.

 

1) Is it correct to understand that the combinational circuit displayed when you right-click the selected LOGIC_CELL_COMB to display properties and select the "F" tab is the result of logic synthesis within LOGIC_CELL_COMB?

 

2) In the blocks displayed when you select the "xxx" tab (xxx depends on the selected LOGIC_CELL_COMB), the input ports seem to be inverted, but this is reversed in the combinational circuit when the "F" tab is selected. Is it correct to recognize that the signal that was sent is being input?

 

Sorry for the elementary question, but it would be helpful if you could teach me.

1) Yes, you are correct.

2) The two equations are opposite in terms of the input signals because the LOGIC_CELL_COMB module in the left figure (xxx tab) has a negation symbol on its input, and the "F" should only apply to the purple part of the circuit. In fact, these two expressions are equivalent, and the left figure should be used as a reference because its input is the actual input from external signals.
