A case when Incubation license was required

 

I came across this strange problem where it started asking for license of Cadence’s Incubation tool.

irun(64): 12.20-s008: (c) Copyright 1995-2013 Cadence Design Systems, Inc.

irun: *W,CSSF: HDL source files with -R option will be ignored.

        Incisive_Incubation 1.0 – license unavailable

ncsim: *F,NOLICN: Unable to checkout license for the simulation. (flag – 42) ‘lic_error -18’.

ncsim: Memory Usage – 26.0M program + 19.2M data = 45.3M total

ncsim: CPU Usage – 0.0s system + 0.0s user = 0.0s total (67.9s, 0.0% cpu)

After a lot of probing and wasting of one whole week, I found that the problem was in trying to do coverpoint on a real variable.

---

 

real percent;

covergroup cg_ABC;

       coverpoint percent {

                bins ….

       }

endcovergroup

---

 

Solution :

I changed it to

int percent;

and simulation stopped asking for Incubation license.

expecting a semicolon

shortint j;

ncvlog: *E,EXPSMC (myClass.sv,106|10): expecting a semicolon (‘;’) [3.2.2(IEEE)].

Problem  : very straightforward, you are missing a semicolon, but where ? right above the line shown, @ 105.

function void myClass::myTask ();
int datacnt = 0
shortint j;
`LOG_MSG (log, LS_DEBUG, $sformatf (” A task to distribute data packets”));

---

 

Solution

function void myClass::myTask ();
int datacnt = 0;
shortint j;
`LOG_MSG (log, LS_DEBUG, $sformatf (” A task to distribute data packets”));

 

 

identify declaration while expecting a statement

int repLines = 0;
|
ncvlog: *E,BADDCL (mySoC.sv,106|5): identify declaration while expecting a statement

---

 

Problem : LOG_MSG should come after declaration of variables

function void myClass::myTask ();
`LOG_MSG (log, LS_DEBUG, $sformatf (“This task will distribute data to all packets”));
int dataCount = 0;
shortint j;

---

 

Solution :

function void myClass::myTask ();
int dataCount = 0;
shortint j;

`LOG_MSG (log, LS_DEBUG, $sformatf (“This task will distribute data to all packets”));
