Below is a list of the strings used and their explanation:
| String | Description |
|---|---|
|
cuk |
Cts: Unknown creator, will not appear in the netlist. |
| ccl_a | Cts: Created during clustering by the agglom clustering algorithm |
| cbi | Cts: Created by the swapping buffers and inverters for power. |
|
cex |
Cts: Existing cells in the tree which cannot be removed. |
|
coi |
Cts: Cells created as a result of cancelling out inversions. |
|
ccl |
Cts: Created by the clustering process to meet the slew target. |
|
ccd |
Cts: Created by clustering for balancing the tree - these cells are not necessary to meet the slew target. |
|
cci |
Cts: Created by the clustering process to fix inversion. |
|
csf |
Cts: Created by the CTS slew fixing step in cases where clustering did not meet the slew target. |
|
cms |
Cts: Created during the process of physically moving clock gates to improve their enable timing. |
|
cid |
Cts: Created by CTS on the outputs of weak driving cells to reduce insertion delay. |
|
cdb |
Cts: Created by CTS to balance the delays in the tree. |
|
cwb |
Cts: Created by CTS to balance the wire delays in the tree. |
|
cfo |
Cts: Created by CTS to reduce fanout skew. |
|
csk |
Cts: Created by the CTS skew fixing step to finely balance the tree. |
|
cmf |
Cts: Created by CTS to buffer long nets. |
|
cbc |
Cts: Created by the trees that cannot be optimized by gated synthesis, such as those parts above RAMs, black boxes, and lockup latches. |
|
css |
Cts: Created by the early cloning of simple sink allocations. |
|
cdc |
Cts: A clock driver created by adding the driver cell process for the add_driver_cell property. |
| cpd | Cts: A clock driver created below an input port or above an output port specified by attribute cts_add_port_driver. |
|
ccg |
Cts: A clock gate created by one of the gated synthesis algorithms. |
|
cse |
Cts: A tree. |
|
cfh |
Cts: A tree. |
| cat | Cts: Created by the add_tree_source_group_roots command |
|

| cpc_sk | Cts : A clock driver created by post conditioning |
| PRO | Post route optimization |
| PRO_drv | Post route optimization |
| PRO_sk | Post route optimization |
| sfc | Cloned by slew fixing |
| ccc | Cts : Created by clone_clock_cells command |
| qrb | Cts: A clock driver created by global route buffering |
| sgb | Cts : A clock driver created by global route buffering |
| idc | Cloned to reduce insertion delay |
| vgb | Cts : A clock driver crated by VG buffering |
| USK | skewClock |
| cff | Cts: A clock driver created by fanout fixing |
| CTSG | Unnamed : this should not be used anymore |
