Hello, 

 

Windows XP 

Quartus: 9.0 32 Bit 

SOPC Builder 9.0 

Prozessor: EP1S10F780C6 

 

I want to change the Clock-Cycle to multi-cycle for my custom instruction, but i can't change it on the SOPC Builder in the Processor custom instruction Tab. 

I use the User Guide: 

http://www.altera.com/literature/ug/ug_nios2_custom_instruction.pdf 

 

on the page 29 is the information: 

 

"The Clock Cycles field indicates the type of custom instruction: 

combinational logic, multi-cycle, extended, internal register file, 

or external interface. If the custom instruction is a fixed length, 

multi-cycle custom instruction, you must edit this field to 

specify the number of clocks. You must determine this number 

based on knowledge of the custom instruction state machine. In 

the case of a variable length multi-cycle custom instruction, the 

Clock Cycles field displays Variable." 

 

but I can not change the clock-cycle 

 

in the setup interface for the custom instruction, on the Tab Interfaces I have the option Clock-Cycle to 15. 

 

please help me 

 

thanks
