Memory Parameter Presets May Not Appear in Parameter Editor

Description

This problem affects DDR2 and DDR3, LPDDR2, QDR II, and RLDRAM II products.

When using the Quartus II software version 13.1, and targeting an Arria V, Cyclone V, or Stratix V device, the Presets list on the Memory Parameters tab of the parameter editor may be empty.

Workaround/Fix

The workaround for this issue is to open each of the following files in a text editor, and change each occurrence of 13.1.1 to 13.1 :

/../.ip/altera/alt_mem_if_ddr2_emif/alt_mem_if_ddr2_mem_model.qprs /../.ip/altera/alt_mem_if_lpddr2_emif/alt_mem_if_lpddr2_mem_model.qprs /../.ip/altera/alt_mem_if_rldramii_emif/alt_mem_if_rldramii_mem_model.qprs /../.ip/altera/alt_mem_if_qdrii_emif/alt_mem_if_qdrii_mem_model.qprs /../.ip/altera/alt_mem_if_hps_emif/alt_mem_if_ddr3_mem_model.qprs /../.ip/altera/alt_mem_if_ddr3_emif/alt_mem_if_ddr3_mem_model.qprs /../.ip/altera/alt_mem_if_rldram3_emif/alt_mem_if_rldram3_mem_model.qprs

For example, in the file /../.ip/altera/alt_mem_if_ddr3_emif/alt_mem_if_ddr3_mem_model.qprs, change:

<ip><presets version="13.1.1"> <preset name="ELPIDA EDJ1108BASE-8C" kind="altera_mem_if_ddr3_emif" version="13.1.1" description="ELPIDA EDJ1108BASE-8C">

to:

<ip><presets version="13.1"> <preset name="ELPIDA EDJ1108BASE-8C" kind="altera_mem_if_ddr3_emif" version="13.1" description="ELPIDA EDJ1108BASE-8C">

This issue is fixed in the Quartus II software version 13.1.2.
