Hi,
When I compile the design, it comes an error: the target library does not contain an inverter. An inverter is required for mapping. (OPT-101)
The db file is converted from a lib manually and the lib file does contain inverter, buffer, and, or gate.
Here is the partial lib of cell INV and the function is !I.
pin (Z) {
direction : output;
function : "!I ";
power_down_function : "(!VDD) + (GND)";
related_ground_pin : GND;
related_power_pin : VDD;
max_capacitance : 0.007;
timing () {
Could anyone please tell me how to solve this problem?
Thanks in advance！
