FPGA IP related clarification in Quartus 13 version

[prabu]

Hi Team,

We are using Cyclone III EP3C40F484C6 device 13.0 version in our project. It is updated from old design that is 9.1 version.

In design , for pwm control accumulator IP is used in 9.0 version. We tried to implement the same design in 13.0 version but could not instantiate ACCUMULATOR (ALT_ACCUM) in qsys window.

Could you please help us to find the accumulator ip . If that ip is not available in 13.0 version, can we use ALTMULT_ACCUM?

but we need addsub control signal for ALTMULT_ACCUM IP. is addsub port available in this IP?

Please help us for this issue.

Hi,

in Quartus 13.1, I have alt_mult_accum available in Megawizard for Cyclone III target, but not e.g. for Cyclone V.

Sorry I misunderstood the question. Quartus 13 clearly states that altaccum is no longer available.

You can either use altaccum design files generated in Quartus 9, or instantiate alt_add_sub with 1 cycle pipeline delay and feed back the output to input a.

May I know if there is any update?
