DDR SDRAM controller Compilations error in Cyclone III

Hi

I have tried to change some , to a . in the SDC file which seems to fix the "invalid number" errors. I have also tried to comment out the line which causes the previous error, but then I get this error:

Critical Warning: Could not find pin of type addrcmd_2t from pattern *ddr_phy_alt_mem_phy_ciii_inst|adc|odt[*].odt_struct|half_rate.addr_pin|auto_generated|ddio_outa[0]|dataout

Error: can't use non-numeric string as operand of "+"

while executing

"expr {$board_skew + $tDS + $WR_DQS_DQ_SETUP_ERROR}"

("foreach" body line 13)

invoked from within

"foreach dqsgroup $pins(dqsgroup) {

set dqspin [lindex $dqsgroup 0]

# DQS output clock

set dqs_out_clockname "${corename}_ddr_dqsout_${dqspin}"

..."

(file "C:/altera/designs/ddr_sdram/ddr_phy_ddr_timing.sdc" line 408)

Critical Warning: Read_sdc failed due to errors in the SDC file

I am not familiar with the syntax in the SDC file so I have not been able to debug it.

Have anybody seen this error before or have a suggestion.

I do not get what I am doing wrong. I cannot find the problem in the Errata Sheet for the DDR & DDR2 SDRAM High-Performance Controller so I must be doing something wrong.

Best Regards

Tom
