RLDRAM II Controller MegaCore Function v7.1 Errata Sheet
Workaround
For VHDL gate-level simulations, in the simulation/modelsim directory
follow these steps:
1.
2.
For Verilog HDL gate-level simulations, in the simulation/modelsim
directory follow these steps:
1.
2.
3.
initial $sdf_annotate("<project name>_v.sdo");
Solution Status
This issue will be fixed in a future version of the RLDRAM II Controller
MegaCore function.
Unpredictable Results for Gate-Level Simulations (HardCopy II
Devices only)
Gate-level simulations may not work as expected on HardCopy
devices, because HardCopy II timing is preliminary in the Quartus II
software version 5.1.
Affected Configurations
This issue affects all configurations on HardCopy II devices.
Design Impact
There is no design impact.
Workaround
This issue has no workaround.
Rename <filename>.vho file to <project name>.vho.
Rename <filename>.sdo file to <project name>_vhd.sdo.
Rename the <filename>.vo file to <project name>.vo.
Rename the <filename>.sdo file to <project name>_v.sdo.
In the <project name>.vo file change the following line to point to the
<project name>_v.sdo file:
