Problem with Co-simulation: Cadence Virtuoso and Matlab

Conhas

When simulate (transient )my design stand alone, it works but when I try to co-simulate it with MATLAB I get the following errors,  please help

Error found by spectre during hierarchy flattening.
    ERROR:  Co-simulation outputs setting error: Unknown error. Check output freqOut.


Time for EDB Visiting: CPU = 6.999 ms, elapsed = 6.19507 ms.
Time accumulated: CPU = 877.866 ms, elapsed = 2.97763 s.
Peak resident memory used = 89.7 Mbytes.

spectre terminated prematurely due to fatal error.

Please Help.

Thank you very very much in advance.

    Thank you very very much for your prompt response.
    When I try to simulate small blocks - they do get simulated without having errors. i.e. i have simulated to the without the last block and I get the desired results.
    The last block (with pin freqOut) also gets simulated in stand alone mode but not when in this configuration.
