Info: Selected device EP3C16F484C6 for design "lock"
Info: Core supply voltage is 1.2V
Info: Low junction temperature is 0 degrees C
Info: High junction temperature is 85 degrees C
Info: Fitter is performing an Auto Fit compilation, which may decrease Fitter effort to reduce compilation time
Info: Device migration not selected. If you intend to use device migration later, you may need to change the pin assignments as they may be incompatible with other devices
Info: Device EP3C40F484C6 is compatible
Info: Device EP3C55F484C6 is compatible
Info: Device EP3C80F484C6 is compatible
Info: Fitter converted 5 user pins into dedicated programming pins

Warning: Some pins have incomplete I/O assignments. Refer to the I/O Assignment Warnings report for details
Info: Timing-driven compilation is using the TimeQuest Timing Analyzer
Critical Warning: Synopsys Design Constraints File file not found: 'lock.sdc'. A Synopsys Design Constraints File is required by the TimeQuest Timing Analyzer to get proper timing constraints. Without it, the Compiler will not properly optimize the design.
Info: No user constrained base clocks found in the design
Info: No user constrained clock uncertainty found in the design. Calling "derive_clock_uncertainty"
Info: The derive_clock_uncertainty command did not apply clock uncertainty to any clock-to-clock transfers.
Info: Timing requirements not specified -- quality metrics such as performance may be sacrificed to reduce compilation time.
Info: Automatically promoted node always0
