VHDL and FPGA basic Questions for a new bee

vhdl basics

dear friends,
i m very new to this topic. and i am Entering into VHDL.
I m a Microcontroller 8051 programmer with "C"
I NEED your advise and suggessions the the confusing questions as follows.

1> is varilog and VHDL are diffrerent ..?

2> In VHDL if i have made any gate ( say NOT gate) by hardware description, after that i need to burn the compiled code into the FPGA ? to behave the FPGA like the gate i described with VHDL ..?

3> what is that end programming methods into the FPGA ..? and any entry level FPGA make Suggession .? plz

3> any ckt dia. available .? to make the FPGA buring board and the software IDE .?

4> ANY book available with --> practical programing of this kind .?

Hope .. my questions are not too much
Thanks in advance for your kind support; friends..!!

vhdl questions

1> is varilog and VHDL are diffrerent ..?

Yes, Verilog and VHDL are two different languages.Verilog has been around longer than VHDL and it is easier to learn.VHDL though is the standard adopted by the US Government.

2> In VHDL if i have made any gate ( say NOT gate) by hardware description, after that i need to burn the compiled code into the FPGA ? to behave the FPGA like the gate i described with VHDL ..?

Yes it will. But it can also be used for creating everything from the humble gates to uC on a single FPGA.

3> what is that end programming methods into the FPGA ..? and any entry level FPGA make Suggession .? plz

FPGAs can be programmed serially inside a equipment or by usin g a JTAG which is a simple circuit you can find on the net.

I use only Xilinx in which Spartan 3 should be good choice for entry level

3> any ckt dia. available .? to make the FPGA buring board and the software IDE .?

There are many resources on the net for that and IDEs are provided free by all the manufacturers so no problem.

4> ANY book available with --> practical programing of this kind .?

Depends on the Language you choose VHDL vs Verilog.

Hope this was helpful.Good Luck

fpga basic

thanks friend .. it was so helpfull and from ur suggessions . i hv desided to learn VHDL and i m goina use aldec software tools for vhdl programming
and spartan3a programming kit i m goina prder to impliment my creations

thanks any way.. for ur suggessions.

just i wanted to know some more things ..


1> is CPLD Better if i program thn FPGA .?

2> whts the difference in fpga and cpld programing in VHDL and PLC and DSP programing -- i mean can DSP and PLC can be programmed my making VHDL program .?

-- thanks

basic fpga

CPLD are EEPROM based.They are slower and can implement less logic than FPGA although they also have some advantages.FPGAs are far more powerful and are SRAM based.

And regarding the second question you cannot program DSP and PLCs using VHDL . VHDL is for making ICs and programming FPGA & CPLD.Besides a FPGA can do anything a PLC or DSP better as here the hardware handles the computation rather than the software.

Hope this was helpful.Post if you have a doubt.

vhdl for fpga

dear friend .. thanks again
i m giving u a lot trouble.. sorry

but i hv some more things to ask hope u dont mind

1> as i know now that as soon as the power is gone.. the FPGA is to be re programmed. in this case.. the boot eeprom can me connected to it to boot the program to the FPGA as soon as the power is applied to thm.
( this is to be forcefully done if we want to impliment an independent system to some place made with FPGA.)
SO MY QUESTION IS -- 1> is thr any ckt dia. available so that this configuration can me achived..?

2> i hv desided to use SPARTAN 3A fpga for the start. is tht ok.?

3> and is thare any sample or advanced programs available for this Fpga From XILINX .? like -- leds and 7 seg. and stepper motors and ADC and other ..

4> is the FPGA can be programed with system c or IMPULSE C ...?

4> IF yes for question 4 then any sample programs available for 7 seg and leds and adc and steper motor ( i mean the peripherals) in C ..?

5> is there the software -->ACTIVE HDL ( any verson) avilable .. with crack .? please share it if you have

thanks a lot friend.. i hope i m not bothering u a lot.

-- thanks in advance

advantages of vhdl on fpga

Yes there are.Any uC with Serial Port can be used see the attached PDF on how to use a 8051 for this.If you don´t want to reprogram then u can use non volatile FPGAs like the Spartan 3AN

Spartan 3A is very good for starting up.If you want a cheap effective FPGA board look at the i want to buy a fpga kit and find the AVNET Board.

You can find tons of programs on the internet.You can search it.Also Opencores in a good start as is Fpga4fun.com check out **broken link removed**

I have never used System C and hence cant comment although I suggest you stick to the course and learn VHDL or Verilog as they are international standards.

Use the EDK provided by your FPGA Maker Xilinx ISE Webpack. It is a 1.5GB Download but it is free and you can implement anything you like
