error after CTS: ERROR:TCLCMD-917

kulprashant

 Hi,

when i read the CTS databese or routed dababase in the encounter, it shows following type of error:

 
**ERROR: (TCLCMD-917):    Cannot find 'clocks, pins, or instances' that match 'ADC_StartConv_DFT_IO' (File /projects/es202b/es202-000/RevA/local/layout/encounter/run.Tata_Netlist_Rev12/new_design/encounter/18Aug_trial/design_db/cts_top_asic.enc.dat/top_asic.pt, Line 2789).

**ERROR: (TCLCMD-917):    Cannot find 'clocks, pins, or instances' that match 'EEPROM_R_eep0' (File /projects/es202b/es202-000/RevA/local/layout/encounter/run.Tata_Netlist_Rev12/new_design/encounter/18Aug_trial/design_db/cts_top_asic.enc.dat/top_asic.pt, Line 4204).

**ERROR: (TCLCMD-917):    Cannot find 'clocks, pins, or instances' that match 'EEPROM_R_eep1' (File /projects/es202b/es202-000/RevA/local/layout/encounter/run.Tata_Netlist_Rev12/new_design/encounter/18Aug_trial/design_db/cts_top_asic.enc.dat/top_asic.pt, Line 4215).

1. i can see this error for all pins (nearly 400 pins design)

2. when i read the placement database then there will be no such type of error. i took same database did CTS and routing and saved.

3. when i will read this CTS or routind data, i got the errors. then i check my confiig file (for the CTS database .enc.dat/") and removed "top_asic.pt" file and then load the config file there was no such errors and then i laod the constraint file (loadTimingCons top_asic.pt), then i git same error

4. In layout all pins are present (dumped the io file and checked).

 Can anyone suggest me what is the cause for such type of error and what is work around to solve this type of problem.

Regards,

Prashant
