Description
The critical warning may be seen in Quartus® II software version 10.0SP1 and earlier when you enable "x36 emulated mode" in the "QDR II and QDR II SRAM Controller with UniPHY v10.0" MegaCore, targeting HardCopy® IV device. This warning is issued due to a problem in <variation_name>_pin_map.tcl generated from the MegaCore.
To workaround, modify <variation_name>_pin_map.tcl by the following steps:
- Locate the following codes:
foreach { k } (k_pins) { kn } (kn_pins) { dq_list } (d_groups) { bws_list } (bws_groups} {
lappend write_pins_list [list ]
lappend write_clock_pairs [list ]
} - Modify the codes as follows:
set k [ lindex (k_pins) 0 ]
set kn [ lindex (kn_pins) 0 ]
lappend write_clock_pairs [list ]
foreach { dq_list } (d_groups) {bws_list} (bws_groups) {
lappend write_pins_list [list ]
}
This issue is fixed in a Quartus II software version 10.1.
