Good evening everyone,
I'm trying to build a small project, which consists of two cascaded PLL's:
The first one First is Integer N-PLL (upstream).
The second one is Fractional N-PLL is (downstream)-it is configurable PLL.
I'm getting error at Fitter such like this:
Error (170084): Can't route signal "PLL_160:U0|PLL_160_0002:pll_160_inst|altera_pll:altera_pll_i|altera_cyclonev_pll:cyclonev_pll|cascade_wire" to atom "ALTCLKCTRL:BUFF_1|ALTCLKCTRL_altclkctrl_0:altclkctrl_0|ALTCLKCTRL_altclkctrl_0_sub:ALTCLKCTRL_altclkctrl_0_sub_component|sd1"
I've tried to put ALTCLKCTRL component or/and GLOBAL primitive between Integer N-PLL cascade output and Reconfigurable Fractional N-PLL adjpplin input-without success.
What is wrong? How can I fix it?
