I've tested the code in codevision (old version, 1.2.37) and the error is because the sizeof function would be evaluated at runtime, but the #define argument should be constant!
If you replace
"sizeof(long)" with 4, you won't get this error. (If A

no put it at the very top level, in your case the schematic of the ring oscillator. if you want to test just one inverter, create a new schematic with just the inverter symbol with the vdd-vdc-gnd circuit and simulate. or replace vdd with vdc=3.3 (or whatever your technology uses) in the schematic of inverter.

AFAIK you would have to create a new symbol with different drive strength or you could replace those symbols which you want to be different with the actual schematic of the inverter and then change the width in those schematics.

I believe the pin swapping information is stored in the schematic/PCB symbol and when you replace the component the pin-swapping information is lost. I seem to recall seeing this mentioned in the Altium PDFs.

What I do is create a new component for the application.
Assuming that if the part is in the schematic, it must have connections some where to the PCB.
Create a new DEVICE using the desired symbol and a new PACKAGE with just the connections you are going to use on the board.
If you have PINS in the symbol that you don't want to show up on

Or place another dummy component, like a documentation symbol at the origin.
then you can ensure that you can replace it where it originaly was.
By the way, what version of Cadstar are you referring to?

yes it is possible. in the schematic and layout you remove all instances of the transformer and replace them with pins (i.e. P1 P2 S1 S2 for primary and secondary coils). Then create a symbol of your circuit and connect the transformer symbol to the pins you added. The only downside is that in postlayout you aren't simulating the extracted (...)

I am working to realize HSP50110 / 50210 architecture, used for demodulation in MATLAB and FPGA. I started with MATLAB's inbuilt example "symbol timing recovery with fixed sampling" and extended the design for HSP50110. I tried to replace Squaring loop method with either Gardner or Early-late Gate algorithm, but no success.

if I understood right you have the new reference library (say newref) with another names of mos transistors.
Then you can proceed next way
1. copy all cells that you are using from oldref to newref
2. disable oldref in cds.lib
3. in your top schematic edit->search->replace: replace all instances with libname=oldref to libname = newref
4. again ed

You replace symbols in schematics, components in PCB.
What Marce said is correct, you need to completely check the symbol, component and part are all correct.

From what you describe its an 18 Ohm, 2Watt resistor ! The size is a bit small for 2W, it is more likely a 1W or 1.5W rating but it depends on its internal construction.
You should find a replacement very easily, its a standard part you can get from most electronic suppliers.
