You will see the following errors during the BSP generation when the Efficiency Monitor is enabled in the UniPHY-based memory controller:
SEVERE: CPU "cpu" has no memories connected to its Avalon master(s)
SEVERE: CPU "cpu" has no memories connected to its Avalon master(s)
SEVERE: nios2-bsp-generate-files failed.
These errors occur because the CPU is unable to identify any connected memory.
The workaround is to set the isMemory Device parameter to true for the Efficiency Monitor.
Modify the following lines in the sopcinfo file:
<assignment>
<name>embeddedsw.configuration.isMemoryDevice</name>
<value>0</value>
</assignment>
<parameter name="isMemoryDevice">
<type>boolean</type>
<value>false</value>
</parameter>
To:
<assignment>
<name>embeddedsw.configuration.isMemoryDevice</name>
<value>1</value>
</assignment>
<parameter name="isMemoryDevice">
<type>boolean</type>
<value>true</value>
</parameter>
This problem is fixed starting with the Quartus® II software version 13.0.1.
