[DRC 23-20] Rule violation (LUTLP-1) Combinatorial Loop - 1 LUT cells form a combinatorial loop. This can create a race condition. Timing analysis may not be accurate. The preferred resolution is to modify the design to remove combinatorial logic loops. To allow bitstream creation for designs...
Now after updating my code, I got error like below,
[DRC 23-20] Rule violation (NSTD-1) Unspecified I/O Standard - 1 out of 13 logical ports use I/O standard (IOSTANDARD) value 'DEFAULT', instead of a user assigned specific value. This may cause I/O contention or incompatibility with the board...
Generally to reduce ac current distortion you can use a inductor also known as chock or reactor. It creates back electromotive force(emf) or voltage as current passes through it and reduces current spikes.
I have task given to design power supply of 1.8V from 5V. using TSMC 0.35um process. I don't know the TSMC 0.35 process.
Is it same as TI PMIC Switching regulator?
I think you connect negative(GND) line at wrong place at XFG... connect it with (-) 3rd pin, and put a resistor between diode diode and XFG positive line.
Yes you can use transistor. But you have not defined your turn off criteria. What if 5V comes it should remain ON or it should turn OFF. What if 2V comes? Please can you specify please?
Strobe signals is kind of self clocking, the time at which data is to be recognized and considered valid. It is used in encoding of data. We can recover clock by XORing of two signal data signal and Strobe signal.
