Help me start doing timing based programs

[kirangowle]

Hi to all,

i am fpga begginer, i have simulated d flip flop, simple gate,basic boolean expressions in quartus II and model sim. Now i want to concentrate on timing issues.timing based programs. so pls guide me how shall i proceed.

Re: FPGA begginer

Hi,

You will need to study processes that are sychronized to the system clock.
VHDL example:

BEGIN

PROCESS ( clk)

BEGIN

IF ( clk = '1' and clk'EVENT)
q <= d;
ENDIF;

END PROCESS;

Look at state machines as well.

You can make a simple memory too.

Re: FPGA begginer

I m trying to build a small development board for my self.
I m planning interface the following resources
1. 16*2 LCD
2. 4*4 Hex key pad.
3. stepper motor( for speed as well as direction).
4. 7 segment display (4 nos)
5.ADC
6.DAC
7. others ( like LEDs, Relay etc)
Kindly help me in selecting which IC(FPGA) should i prefer for above devices to be interference.
Whether i require External EPROM and SRAM to program this?

You may want to copy existing Dev. Kit circuits, or modify them according to your needs. But I would strongly advice
against it unless you are really experienced with PCB design and prototype assembly. Some vendor's Dev. Kits
have sponsored retail prices that can be hardly beaten by buying the components yourself, not considering
the PCB production and assembly effort.

It's different of course if you're required to design a board with a specific functionality like a product or subsystem prototype.

Re: FPGA begginer

No. i m trying to modify the existing board to my requirement.
Because i dont know where i can get customized one.
So kindly pls suggest me..what are the peripheral i require.

Re: FPGA begginer

Can anyone suggest me where i can get the customized FPGA boards. i mean local suppliers in Bangalore, India.

Re: FPGA begginer

Why dnt u hook up with some development board for ur design, the things u have written all available with Xillinx Spartan 3E development board from digilentinc (Digilent Inc. - Digital Design Engineer's Source), Collect that and start designing rather making ur own development board and stuck with PCB designing then FPGA designing!
