Variable as real

i have to find velocity with Quadrature decoded singnal. the equation is
velocity =(60*y)/(36*30), Where y is the count which is an integer variable.when i declare the velocity as "Real" i got compilation error message "non constant real variable cannot synthesize". how can i get fractional values of velocity?

fpga and steppermotor

tell me that how many stepper motor can be controlled byfpga spartan ii

7segment

I need to display different numbers on the 7segments that are on the fpga according to the input I have. For example if I want to display the number 250, 2 on the 1st segment, 5 on the 2nd and 0 on the 3rd... How do I do it in VHDL pls?

Till now I am only capable of displaying the same number on all of the segments. My fpga is a spartan 3e-100

If anyone could help me I would really appreciate.

punch through devices

What are punch through devices? What are there advantages? Is there any advantage if we use them as memory devices?

BJT vs. MOSFET gain comparison

for a mosfet in common source configuration
voltage gain A_mos = -gm*(ro||RD||RL)

and for a BJT in common emitter configuration,
A_bjt = -gm*(ro||RC||RL)

where, ro = output resistance = VA/IC or ID, VA=early voltage, IC=bias collector current and gm =transconductance parameter

considering RC=RD and load, RL to be the same, what can be said about the relative values of A_mos and A_bjt. What would be the comparitive relation between the values of gm and ro of both devices in general.?

Current Mirror vs. Current Source

Please explain to me the difference between a normal current source and a current mirror(using Mosfets or BJTs).. What advantage does a current mirror offer over a normal current source. Why cant we directly use the reference current used in current mirrors for biasing or other purposes. is it because of lower output impedance that a Mosfet offers and thus lesser dependence of output current on load..??
