System not generating with 2 clock sources

having played about some more with sopc builder i have noticed that if my counter module is running at a different frequency from the cpu then the system will not generate.

if i have my counter module and cpu running at 100mhz, i can run the system id peripheral, jtag uart, ram etc at 10mhz and the system generates correctly. if i try and run the counter at 10mhz then the system will not generate.

has anyone experienced similar problems?

I have a similar problem, because when generating the SOPC builder system I get the message:

------------------------

...# 2007.01.11 08:32:23 (*) Running Generator Program for clock_0# 2007.01.11 08:32:26 (*) Running Generator Program for clock_1# 2007.01.11 08:32:29 (*) Running Generator Program for clock_2

ERROR:

no width for slave_nativeaddress

Error: Generator program

for module &#39;clock_2&#39; did NOT run successfully.

...

------------------------

The external input clock is 24 MHz, the first pll has an internal clock output with 25MHz, another with 40MHz and an external clock output with 40MHz. The second pll has an internal clock output with 27MHz, another with 108MHz and an external clock output with 108MHz. The external clock outputs are not used inside the SOPC builder system. Therefore the questions:

1.) The PLL Megafunction Wizard says &#39;Able to implement the requested PLL&#39;, so why this error?

2.) Where can I set the width for the slave_nativeaddress?

@boydal:

Did you find a solution for your problem? Just changing the Frequency and the system could be generated or what?

Thanks for any help!
