VHDL Seek help

Can anybody help me how to program a descending rotation using a vhdl. The output must be display through a 7-segment. The values required to be displayed are as follows "9-5-1-C-8-4-0". Is there somebody can help me here....thx...

1. Write VHDL code for a counter. Add conditions to the simple counter to count only from 0 to 6, with some kind of reset for repetition if you want that.
2. Figure out the output values necessary to form each character you want to display.
3. Write the VHDL code that uses the counter to set the desired set of output values based on the counter value.
4. If your clock frequency is too high (too fast), write VHDL code for a clock divider to create a slower internal clock.

If you want actual VHDL sample code, ask your teacher.

yer, if that is the only sequence you need to produce just make a simple state machine (ie a counter from 0-6) which is clocked with a clk at the correct down-sampled rate (from main clk).

Then just simply do:

if state == 2
output1 = 0
output2 = 1
...
output7 = 1

if state = 1
output1 = 1
output2 = 1
...
output7 = 0


simplest way. Sorry no where near a VHDL simulator to actually knock together a full state-machienfor this
