  1. To run the RTL simulation, perform the following steps: • Open Modelsim. • Move into the directory ./HMC/testbench/mentor • Run "Source msim_setup.tcl" in the console• Run "dev_com" • Run "com" •
  2. And that is why user have to use set_clock_source() to set up/select the one of them as the source.

  6. This is to allow single master to control two controllers.
  7. However, you still can bond two HMCs with same memory configuration with different data width.

Here is the link to your error from Altera's website: http://www.altera.com/support/kdb/so...82014_665.html First try the approach that they give on that link.

Select Disabled for Memory additive CAS latency setting. We are sorry. You may have to register before you can post: click the register link above to proceed. The function of this block is to process two sets of avalon signals from two bonded hard memory controllers to the single master (pattern generator).

Same bonding guidelines is applicable to Cyclone V hard memory controller.This design is generated in Qsys flow. So I think the arch maybe based on Fig. 2 (0-delay dual PLL) of the LMK04816 manual (http://www.ti.com/lit/ds/symlink/lmk04816.pdf) and this chip takes CLKin1 as a reference clock.

Once two identical hard memory controllers are generated, connect the bonding_in and bonding_out port for both controllers as shown in figure below.

For example, you can bond a single 16-bit HMC with another 32-bit HMC to form a 48-bit interface provided both HMCs are same memory configurations.
