Hi,

I am trying uvm_do_on_with to run i2c sequence on master sequencer and getting below syntax error . Can you please help on this ?

SEQUENCE CODE ------------------------------------------------------------------------------------------------------
// uvm_do_on_with(i2c_mst_seq,svt_i2c_master_transaction_sequencer, uvm_do_on_with(i2c_mst_seq,m_env.i2c_env.i2c_system_env.sequencer.master_sequencer[0],
{
i2c_mst_seq.lcl_cmd == I2C_WRITE; i2c_mst_seq.lcl_addr == I2C_SLAVE0_ADDRESS;
i2c_mst_seq.lcl_data_size == 5;
i2c_mst_seq,lcl_sr_or_p_gen == 0;
i2c_mst_seq,lcl_send_start_byte == 0;
})

In reply to as1494:

You are showing only the error message. We do not see the source code, especially the sequence code. This does not allow to give you a good advice.

In reply to chr_sue:

I added sequence code and syntax error comes at uvm_do_on_with line -

 task body();

uvm_do_on_with(i2c_mst_seq,m_env.i2c_env.i2c_system_env.sequencer.master_sequencer[0], { i2c_mst_seq.lcl_cmd == SVT_I2C_WRITE;
i2c_mst_seq.lcl_addr == `SVT_I2C_SLAVE0_ADDRESS;
i2c_mst_seq.lcl_data_size == 5;
i2c_mst_seq,lcl_sr_or_p_gen == 0;
i2c_mst_seq,lcl_send_start_byte == 0;
})

 `uvm_do_on(wait_until_driver_idle_seq,p_sequencer.root_virt_seqr.driver_seqr[0]);

 endtask

Thankyou !

You have a comma instead of a dot in the last two constraint lines between i2c_mst_seq and lcl.
