Hello,
Have designed a simple resonator circuit to model an antenna. But I am getting errors when I tried to simulate it in cadence.
Have attached the design for your reference.
************************************************** ***********
Notice from spectre during topology check.
No connections to node `0'.
No DC path from node `net2' to ground, Gmin installed to provide path.
Fatal error found by spectre during topology check.
FATAL: The following branches form a loop of rigid branches (shorts) when added to the circuit:
V0:p (from net2 to gnda!)
Aggregate audit (2:57:02 PM, Thur Aug 25, 2011):
Time used: CPU = 147 ms, elapsed = 198 ms, util. = 74.2%.
Time spent in licensing: elapsed = 50.9 ms, percentage of total = 25.7%.
Peak memory used = 8.13 Mbytes.
spectre completes with 1 error, 0 warnings, and 2 notices.
spectre terminated prematurely due to fatal error.
