Libraries not imported in the Library manager

I see no reason why that should not work. Are you sure that you have the UNIX environment variables UCDPRJDIR and UK_CDS_PREFIX set?

In the unlikely event that it was broken in a specific subversion of IC617, which exact subversion are you using (Help->About will tell you this, or the result of the getVersion(t) function in the CIW).

Regards,

Andrew.

Thanks for your quick reply. It's verified that the Cadence is IC6.1.7-64b.500.21.  By the way, how can I be sure I have the UNIX environment variables UCDPRJDIR and UK_CDS_PREFIX set? Thanks in advance.

Regards,

UU

I checked that version and it works fine for me with that precise SOFTINCLUDE (provided I have the environment variables set, and a suitable file available for it to include, of course).

You can check the env vars are set in your setup by typing:

getShellEnvVar("UCDPRJDIR")
getShellEnvVar("UK_CDS_PREFIX")

in the CIW. If these return nil, the env vars aren't set; if they return a string, they are set.

Regards,

Andrew.

Thanks very much. It's verified that they are set, so we just insert the libraries by hand in the cds.lib file, not by SOFTINCLUDE. 

I don't see why that should be necessary, assuming that the "cds.lib" file (with resolved env vars) exists. Whilst you have a workaround, if you want to resolve this, the best thing would be to contact customer support so that we can take a look in more detail to work out why this is not working for you.

Regards,

Andrew.

Thanks very much. We will check again and contact the support.

I have another question about this library. When we used this library(cmos045) in Cadence 615 and 616, it worked well. But recently we tried to implement the library in the same way in Cadence IC6.1.7-64b.500.21. There are several problems. The installation goes well, but the simulation has encountered proble. The details are as follows:

In the « .simrc » file, the switchviewlist and stopviewlist are defined as follows :

;;;;;; UNICAD update of .simrc begin ;;;;;;

UkerSimrc = t

loadi(strcat(getShellEnvVar("UNICAD_KERNEL_ROOT") "/Uker.ile"))

UkerSimrc = nil

;;;;;; UNICAD update of .simrc end ;;;;;;

loadi( strcat(getShellEnvVar("PDKITROOT") "/" "PDK_STM_cmos040lp_AMS_7m4x0y2z_2V51V8.simrc"))

asiSetEnvOptionVal(asiGetTool('spectre) "switchViewList"

list("SimMosfetStandard" "SimDiodeStandard" "SimCpolyStandard" "SimCmetalStandard" "SimCfringeStandard" "SimCfringeAccurate" "SimResistorStandard" "SimResistorAccurate" "SimResistorHF" "SimResistorHFV" "SimBipolarStandard" "SimCmimStandard" "SimCapaStd" "SimCapaAcc" "SimMosfetAccurate" "SimMosfetrfStandard" "SimMosfetrfPSP" "SimInductorStandard" "SimInductorAccurate" "SimVaractorStandard" "SimCmomStandard" "SimCmomAccurate" "hspiceS" "hspiceD" "auCmos_sch" "cmos_sch" "cmos.sch" "ads_schematic" "schematic" "auGate_sch" "auGate.sch" "gate_sch" "gate.sch" "extracted"

))

asiSetEnvOptionVal(asiGetTool('spectre) "stopViewList"

list("SimMosfetStandard" "SimDiodeStandard" "SimCpolyStandard" "SimCmetalStandard" "SimCfringeStandard" "SimCfringeAccurate" "SimResistorStandard" "SimResistorAccurate" "SimResistorHF" "SimResistorHFV" "SimBipolarStandard" "SimCmimStandard" "SimCapaStd" "SimCapaAcc" "SimMosfetAccurate" "SimMosfetrfStandard" "SimMosfetrfPSP" "SimInductorStandard" "SimInductorAccurate" "SimVaractorStandard" "SimCmomStandard" "SimCmomAccurate" "hspiceS" "hspiceD"

))

 asiSetEnvOptionVal(asiGetTool('spectre) "modelFiles"

list( strcat(getShellEnvVar("PDKITROOT") "/" "/SIMU/SPECTRE/ST/corners.scs" )

But when we perform a simulation, the two lists in the environment settings appear like :

spectre cmos_sch cmos.sch schematic veriloga

spectre

When we run the simulation, the error in the CIW is :

ERROR (OSSHNL-116): Unable to descend into any of the views defined in the view list, 'spectre cmos_sch cmos.sch schematic veriloga', for the

instance 'M0' in cell 'inverter'. Add one of these views to the cell 'nlvtlp' in the

library 'cmos045', or modify the view list so that it contains an existing view.

When 'SimMosfetStandard' is added into the switchviewlist, there is no output, and the warnings in “spetre.out”  file are:

 Warning from spectre during AHDL read-in.

    WARNING (VACOMP-2435): The environment variable CDS_AHDLCMI_ENABLE is no longer supported. Therefore, the simulator will use the default compiled C code flow.

 Warning from spectre during hierarchy flattening.

WARNING (SPECTRE-17101): The value 'psf' specified using the 'checklimitdest' option will no longer be supported in future releases.

The warnings in CIW are:

WARNING (OSSHNL-117): Ignoring switch view 'SimMosfetStandard' of cell 'nlvtlp' in library 'cmos045', as it does not contain

any instance. To netlist this cell, add this switch view to the stop list or to

ignore any specific instance set the property 'nlAction' to value "ignore" on

this cell view.

WARNING (OSSHNL-117): Ignoring switch view 'SimMosfetStandard' of cell 'plvtlp' in library 'cmos045', as it does not contain

any instance. To netlist this cell, add this switch view to the stop list or to

ignore any specific instance set the property 'nlAction' to value "ignore" on

this cell view.

When the switch lists and stop lists in the  « .simrc » file are injected by hands, the errors appear like :

Netlist Error: Could not find netlist procedure:UartDirectSubcktCall instance "M0" in cell-view "Test" "inverter" "schematic"

Netlist Error: Could not find netlist procedure:UartDirectSubcktCall instance "M1" in cell-view "Test" "inverter" "schematic"

So, in your opinion, is it possible that the Cadence 617 does not support this library? Thanks very much in advance. 

Best regards,

UU

This is very specific to the UNICAD (ST) environment. You would be better off contacting ST Microelectronics for support, since it's their design kit and design environment that is involved here (I can't comment on whether there's anything in that environment that is overriding the switch view lists etc, or why the netlist procedure is not loaded).

Regards,

Andrew.

Thanks very much.
