can anyone suggest me how to write a VHDL code to control or monitor voltage, temperature and current in IGBT gate drive via Quartus II cyclone development kit EP2C20F484C7N fpga..???

No, they cannot, you haven't really provided any information, or any indication that you have done a little research.
FPGAs are digital devices, with logic level I/O pins.
How does the IGBT need to be controlled? On/off control, PWM control, or what?
Monitoring voltage, and current can be done using an analog-to-digital converter (ADC). Temperature can be measured using a temperature sensor with an internal ADC, or with another ADC and a voltage-output sensor.
There are plenty of SPI ADCs that are easy to interface to FPGAs.
My recommendation would be to first get your IGBT circuit designed in a simulation program like LTspice, using ideal voltage sources (configured for PWM generation if necessary), and voltage/current sense points in the design. Post that circuit, and it'll be clearer what voltage levels and currents need to be sensed. If you have analog circuit design questions, then ask those on the LTspice group (though if they are not LTspice related, you may get referred to an electronics design group).
